Mercury is the closest planet to the SunIt resembles the moon in that it has impact craters on its surfaceIt has a crater called the Caloris Impact Basin which is the size of TexasMercurys molten core is larger than Earths core relative to their respective planet sizesThe temperature on Mercury varies by around 600 degrees C between day and nightMercury has the most elliptical orbit of any planet in the Solar System
The surface of Venus is hot enough to melt lead!However, its composition is very similar to EarthsAtmospheric composition:96.4% carbon dioxide3.4% nitrogen0.015% sulfur dioxide0.007% argon0.002% water vaporIt is frequently referred to as the morning or evening star, as it can be seen in the sky right after the Sun rises or sets.Home Pagehttp://nssdc.gsfc.nasa.gov/planetary/image/venus_magellan.jpghttp://nssdc.gsfc.nasa.gov/planetary/factsheet/venusfact.html4
Earth formed approximately 4.54 billion years agoMore than 70 percent of the Earth is covered in water.Atmospheric Composition:78.084% nitrogen20.846% oxygen0.9340% argon0.1 % water vapor0.039% carbon dioxideMinimal percentages of neon, helium, methane, krypton, hydrogen, nitrous oxide and carbon monoxideThe Earths lithosphere (solid outer layer) floats on molten magma.Earths moon is the largest moon relative to the planet that it orbits in the Solar SystemHome Pagehttp://solarsystem.nasa.gov/planets/profile.cfm?Object=Earthhttp://solarsystem.nasa.gov/multimedia/display.cfm?IM_ID=96435
Mars is known as The Red Planet.The temperature on Mars barely reaches 0 degrees C on a summer dayThere has been evidence found on Mars of the existence of waterThis leads to possibilities of life, such as microorganisms, existing there.Mars is home to Olympus Mons, the largest volcano in the solar system it is three times the height of Mount Everest!
Jupiter is the largest planet in the solar system.It is a gaseous planet that is more than three hundred times the mass of the Earth.It has a Great Red Spot, which is actually a hurricane three times bigger than our planet, that has been going on for at least 200 years.If you managed to travel to Jupiter, the first thing that you would come across would be an invisible force field.The core of Jupiter is thought to be solid, and around the size of the EarthHome Pagehttp://solarsystem.nasa.gov/planets/profile.cfm?Object=Jupiter7
Saturn is the second largest planet in the Solar SystemIts diameter is ten times that of the Earth and it is ten times further away from the Sun.Saturn has 53 known moons, and has 9 moons that have been discovered and are waiting to be confirmedSaturns Great White Spot is a giant storm, similar to Jupiters Great Red Spot.However, Saturns Great White Spot is not always there, and only shows up intermittently, around every 30 years.Saturns rings are so thin that they appear to vanish when they are looked at straight on the edge.Home Pagehttp://nssdc.gsfc.nasa.gov/image/planetary/saturn/saturn.jpghttp://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-saturn.html#saturn8
When Uranus was first discovered, it was mistakenly catalogued as a starUranus is the name of the father of the Roman god SaturnUnlike any of the other planets, it spins on its side, with its northern hemisphere facing the Sun for 42 years of sunlight, before turning the other way and experiencing 42 years of darknessUranus has 27 moons named after various characters from works of William Shakespeare and Alexander Pope
Neptune is the eighth planet from the sunNeptune is made up mostly of hydrogen and helium, with a small amount of methaneNeptune is blue because the methane in its atmosphere absorbs red light from the Sun, but reflects blue lightNeptune has 13 moons which are named after different sea gods and nymphs in Greek mythology
