The Solar System
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
