Our Solar System In order • Mercury • Venus • Earth • Mars • Asteroid Belt • Jupiter • Saturn • Uranus • Neptune • Kuiper Belt • Oort Cloud
Terrestrial Planets • Mercury • Venus • Earth • Mars • All have a rocky crust, a denser mantle, and a very dense core
The Jovian Planets • Jupiter, Saturn, Uranus and Neptune • A solid rock core • A liquid mantle • An outer gas layer • A ring system
Mercury: Closest to the Sun • 1 solar orbit takes 88 days • Rotates on axis every 58.6 days • Temperatures range from 425 degrees C to -150 degrees C
Venus: The 2nd Planet • Atmosphere is made of sulfuric acid clouds and CO2 • Surface is covered in faults, lava, and volcanoes • Temperatures in excess of 480 degrees C
Mars: 4th from the Sun • Has polar ice caps made mainly of CO2 • 27 degrees C during the day -125 degrees C at night • Orbits the sun every 637 days
Jupiter: The 5th Planet • Takes 11.9 years to orbit the sun • Surface is made of alternating light/dark bands of gas
Saturn: The 6th Planet • 29.7 years to orbit the sun • Known for its rings, which are made of rock and ice
Uranus: The 7th Planet • Takes 84 years to orbit the sun • -200 degrees C
Neptune: The 8th Planet • 165 years to orbit the sun • Gives off 2.7 times more heat than it receives • Fastest wind in the solar system (2200 km/hr)
Asteroid Belt • Asteroid: Solid rock masses floating in space • Asteroid Belt: Zone of multiple asteroids between Mars and Jupiter
Kuiper Belt • Area of objects from the orbit of Neptune (30.1 AU) to 50 Au from the sun • Smaller objects, hard to see and identify (size & light)
The Oort Cloud • Outer most area of our solar system • 50,000AU to 100,000AU distance from the sun • Spherical cloud of comets
Comets • A mass of rock, gas, and dust that orbits the sun • Usually has a highly elliptical orbit • Tail is caused by solar wind flying past the body of the comet
Meteors, Meteoroids, & Meteorites • Meteoroids are any rock or ice fragment traveling in space • A meteor is the light made when a meteoroid passes through our atmosphere • A meteorite is any piece of a meteoroid that survives its trip through the atmosphere and hits our surface
