...slider all the way to accurate, click on the tape measure and the grid. 2. Click the radio button for 4 objects and run the simulation until the purple planet (body 2) has made one complete orbit (one year). 3. After the first orbit (year), turn off the traces (show traces box) and watch another orbit (year) of the purple planet (body 2). Question One: Is blue moon (body 3) circling the yellow sun (body 1) or the purple planet (body 2)? Explain your answer. The blue moon is circling the purple planet, because it is constantly in that planets orbit. The purple planet though is circling the yellow sun making it seem almost like the blue planet is circling it as well. 4. Increase the mass of the sun (body 1) to 400 and allow the simulation to run for one complete orbit of the purple planet (body 2). 5. Decrease the mass of the sun (body 1) to 175 and allow the simulation to run for one complete orbit of the purple planet (body 2). (~90 seconds) Question Two: How do the orbits of the planets change when the mass of the sun is increased or decreased? Why? Explain your answer. Wen the mass is 400, the planets will circle the sun much closer, because it has a much stronger gravitational force due to its large mass compared to the smaller planets. When the mass is smaller, the radius that the planets circle is much bigger because there is less gravitational force on them, and they circle the sun at a much slower speed. Question Three: ...

...PLANETS By Reanna Hinson The purpose of my project and essay is to familiarize ourselves with the different planets within our own solar system. I will present different, unique and amazing facts about each the eight planets. My project also displays a colored example of what each planet appears to look like as well as statistical information. Mercury, Venus, Earth, and Mars, are called the terrestrial planets because they have solid rocky surfaces. Jupiter, Saturn, Uranus, and Neptune and are called gas giants. Earth is the only planet of the eight that has life forms as we know them. All other planets have extreme conditions such as temperatures, atmospheres and weather that make life as we know it impossible to exist, but we still keep looking for alien signs of life. Mercury Mercury is a small planet that spins very slowly in orbit around the sun. It is the planet closest to the sun and has extreme temperature changes. During the day the temperature can soar to 870° Fahrenheit and at night time down to -300° Fahrenheit. Mercury has no moons and a very small and weak atmosphere because the Sun’s solar winds have blown it away. This causes very little to no air on Mercury. Venus Venus and Earth are just about the same size, but Venus always has a thick cloud cover making it impossible to see the surface of the planet, and traps a lot of the Sun’s heat making it the hottest average temperature of all the planets. The average temperature is 850° Fahrenheit...

...The poem "Warned" by Sylvia Stults, is a poetic take on the destructive nature of the human race. She uses a rhythmic pattern of the sonnet to describe the beauty of our planet along with the destructiveness that is breaking down nature. The poem is revered as sympathetic to the audience and evokes a sense of compassion and longing for change. It is devastating to hear all the ways people have polluted our once luxurious planet. This poem allows the readers to think more clearly about how to treat our environment. If the people continue this road of self destruction there may not be to much of earth left to cherish. By becoming more aware of the environment and the everlasting consequences of our actions we can begin to take the necessary steps to preserve the wilderness, protect wildlife, and create a better future....

... where its magnetic field lines pierce the surface of the Sun. Sunspots can be the source of solar flares and coronal mass ejections. core The Earth core is the innermost, hottest part of the planet that has been detected by seismological study. It is a primarily solid sphere about 1,220 km in radius. It is thought to be made up of an iron-nickel alloy with a temperature similar to the surface of the Sun (5,778 K). The make-up of the inner core can be deduced from the abundant chemical elements in the solar system. There are two layers to the core * Inner unconnected * Outer The existence of an inner core distinct from the liquid outer core was discovered in 1936 using observations of seismic waves that partly reflect from its boundary. The outer core was believed to be liquid due to its inability to transmit elastic shear waves. It only allows compressional waves to pass through it. The solidity of the inner core has been difficult to establish, because the elastic shear waves that are expected to pass through it are very weak and difficult to detect. Mercury is the innermost and smallest planet in the Solar System,[a] orbiting the Sun once every 87.969 Earth days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. It completes three rotations about its axis for every two orbits. Venus is a dim world of...

It is a vacation planet for all types of people if you like snow, leaves, sunshine, or rain. Life thrives there. This planet is the most perfect planet scientist have created so far. It has one moon that orbits around it so we have high and low tides, like on Earth, however, there are more tides because the moon is closer and moves faster, it is easy to sustain life due to its atmosphere, it is orbiting a star, and has little to no weather change. On Planet_Manufactured-372 A the Milky Way Committee have created an atmosphere by keeping a stable amount of gravity that keeps our atmosphere around us.The...

...On september 23rd, 1846 two astronomers John Couch from Britain, And Urbain Le Verrier from France joined together and used calculations to find the exact location of of Neptune. They both claimed they found it and it lead to an national dispute. Neptune is the eighth planet the solar system. Uranus is in front and Pluto is behind it. The planet takes 15 hours, 57 minutes and 59 seconds to fully rotate. That is a little faster than Earth's rotation. Now before you see how many miles large it is I will tell you that it is three point nine times larger than earth. It is 5,299 miles. And its mass is 17 times larger than Earth's mass, Its gravity is 11.15 m/s. So if you weigh 100 pounds on earth you would weigh 110 pounds on Neptune. Its takes...

...me is basically just a way of thinking. When thinking scientifically, you look at all the data and evidence before you make a conclusion, and you compare and contrast data and evidence. You would also be prepared to change your decision when new data or evidence is presented. For example, when scientists discovered Pluto, they first thought it was a planet, until 76 years later, in 2006. Scientists later discovered many other minor planets such as Chiron, and became suspicious. By 2006, they changed Pluto into a dwarf planet. When something is unknown, scientists are able to make hypotheses as to why and how. Then they make controlled experimentation or join data together to disprove or prove the hypothesis. This is science to me. When I think of scientist, I think of a man in a white suit, with blue gloves, and protective glasses. Doctors and scientists have many similarities including the way they dress. Doctors wear white suits and blue gloves because it is sanitary and they can see if they spilled anything on them. A doctor and scientist looks mainly the same to me and that is why I imagine a scientist with a white suit and blue gloves. I imagine a scientist as someone measuring and studying human bones or blood samples. I think of a forensic scientist, who studies evidence and gathers data. When I was younger, I was interested in forensic science, and I watched a show with my grandpa called Forensic Files. When I was little, the pictures of forensic scientists always reminded...

These stars have a very large gravitational pull that holds everything in place, planets also have a gravitational pull but it's not as powerful as the sun's gravitational pull, which makes it so that the planets do not float away but also do not come crashing into the sun. Stars are immense balls of gas that produce...

...Conservation Biology is defined as the scientific study of the nature and status of Earth’s biodiversity. The main aim is protecting species, their habitats, and ecosystem from overly fast growing extinction rates. Biodiversity is defined as the variety of organisms that occupy a specific region. This includes all organisms from that region, the smallest creature to the largest mammals. The earth is a vast planet, which is growing and changing every day. Many things are out of our control, but there are also many things that are within our control. People play a direct impact on the environment as well as the wild life. Unfortunately a lot of our negative actions have led to the extinction of various species. Animals can be broken down into three different species, threatened, endangered and extinct. Threatened Species can be defined as a species commonly found in an area, that is at high risk of becoming endangered. "A threatened species may have a declining population or be exceptionally rare. Similar to endangered species, the cause of their decline is based and various factors such as habitat destruction, climate change or the introduction of an invasive species to their natural habitat" (Buchanan,M.). A good example of a Threatened Species is the Loggerhead Turtle. They are found globally, preferring temperate and subtropical waters. Loggerhead turtles and their eggs are hunted extensively in many parts of the world. "However, the main threat is from raccoons and...

...NASA's Chandra Sees Eclipsing Planet in X-rays for First Time For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star. An advantageous alignment of a planet and its parent star in the system HD 189733, which is 63 light-years from Earth, enabled NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM Newton Observatory to observe a dip in X-ray intensity as the planet transited the star. "Thousands of planet candidates have been seen to transit in only optical light," said Katja Poppenhaeger of Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led a new study to be published in the Aug. 10 edition of The Astrophysical Journal. "Finally being able to study one in X-rays is important because it reveals new information about the properties of an exoplanet." The team used Chandra to observe six transits and data from XMM Newton observations of one. The planet, known as HD 189733b, is a hot Jupiter, meaning it is similar in size to Jupiter in our solar system but in very close orbit around its star. HD 189733b is more than 30 times closer to its star than Earth is to the sun. It orbits the star once every 2.2 days. HD 189733b is the closest hot Jupiter to Earth, which makes it a prime target for astronomers who want to learn more about this type of exoplanet and the atmosphere around it...

...Planetary Comparison SCI/151 May 3, 2011 Norman Stradleigh Planetary Comparison Planet Earth is the third planet from the Sun and the fifth largest of the planets of the Solar System. Earth’s surface is 71 percent water and is the only astronomical planet currently known where life exists. Earth is our home planet. Scientist and astronomers have studied our planet for Centuries and they have discovered much about our planet. Scientist have gained so much more knowledge of our Solar System in the last half-century after the NASA launched the first spacecraft and travel beyond Earth’s atmosphere has opened up to those who wish to explore. In the following paragraphs, we will discuss Earth and the comparison between the other known planets in our Solar system. Earth has several layers that have distinct chemical and seismic properties: Crust, Upper mantle, Transition region, Lower mantle, D’’ layer, Outer core, and Inner core. The crust, the part we inhabit, is just a tiny fraction of the Earths mass. Most of the mass of the Earth is in the mantle, a majority of the rest is in the core (Nine Planets, 1994-2010). Earth has three layers of density: The core primarily metals, such as nickel and iron, resides in the central core and is the highest-density material. The Mantel forms the thick mantle that surrounds the core is mostly minerals that contain silicone, oxygen, and other elements and is a rocky material of modest density....

...mosJessica Lorge Cosmos 11 April 2012 The Pale Blue Dot Carl Sagan puts it perfectly, Earth which has and will consist of everything and everyone we will ever directly know is on this mote of dust suspended in a sunbeam. How does one look at the world once we realize our position in regards to the whole universe? I thought there were so many people on this Earth but that everything that goes on in my one life was important....but once I saw how large the universe is and started considering my position I feel smaller and smaller. The Sun is one hundred and fifty million kilometers from Earth and the Sun is one million times the size of Earth. There is still light traveling to Earth set out by galaxies billions of years ago. There are approximately seven billion people on this planet. Do you feel small yet? For a long time not a lot of people considered how small the Earth was in comparison to the whole universe, and for those who did, they did not take into consideration the significance of our planet or lack thereof because the churches controlled basic human thought. The idea that human's on Earth were not at the center of the universe and the most important thing out there when we began discovering sunspots, irregular orbit patters of planets and moons, and that the planets did not revolve around the Earth. It's interesting how we as human's think that we are the basis for reality and that everything revolves around us. Why do we think that the natural world and universe...

...Theologian from Planet X on the outskirts of the Milky Way galaxy. I have been commissioned by officials on my home planet with traveling to earth to study the religions of that world. On my planet, religion is a way for our government to control the citizens of our world. Our religion requires total submission to the government and leaders of the planet. We want to know if earth has a similar system in place and it is my responsibility to examine behaviors and beliefs there, determine the function of religion on the planet, and report back to those who have sent me. I am going to be looking for behaviors from the earthlings such as belief in a creator or creators of their race. The citizens of Planet X believe that our world was created by beings called Zenids. The story we have given our people says that the Zenids came from another world to Planet X when it was uninhabited and spawned life there. Our leaders beleive that life on our planet was a result of natural phenomena and evolution. I will be looking for a similar belief in higher power on earth. The citizens of Planet X pray to the Zenids and adhere to the scriptures handed down to them that detail the story of creation and the laws that the Zenids require our people to follow. To us, religion is the belief in higher power, prayer to this higher power, and belief in scriptures handed down by the higher power or through those inspired by the higher power. As I travel this blue planet at speeds that...

I do not know exactly where we were but it was already night when I positioned myself at the docking compartment window. I think it was the one facing more starboard. I always get myself mixed up when I go into that module; I can never easily find the hatch again. It is completely night. There are thunderstorms across Africa and lightning is everywhere; bright flashes are going cloud to cloud illuminating the clouds as it arcs from one to the other. It is a private fireworks show. The storm is large and very spread out and at any moment you see 4 or 5 flashes occurring at one time, each one only lasting a moment. The colors range from something orange-ish to blue-white. Some are more like balls of light while others have that characteristic streak shape that you can observe on Earth. It goes on for several minutes. Occasionally a city goes by with lights shining brightly against the backdrop of flashing pulses of light. The cities come in all shapes, sizes and colors and light patterns. Some cities have clouds over them and all that can be seen is a haze of light. For the cities with clear skies, street patterns are apparent...
