|
|
Planet Venus |
-has 0 moons -is 2nd in the solar system -surface is rock -has greenhouse effect due to cloud cover and is hot enough to melt lead -retrograde rotation (rotates the opposite direction of other planets) -has extreme pressure, temperature, and winds at its surface |
|
|
Planet earth |
-has 1 moon -is 3rd in the solar system -it’s surface is made of rock -only planet with a lot of water -only planet known to have life -you live here
|

|
Planet Mars |
-has 2 moons -is 4th in the solar system -surface is rock -has a red surface due to iron oxide -has polar ice caps of water and frozen carbon dioxide -has canals probably formed by lava flows -is studied a great deal with probes in preparation of (one way) planned manned mission |
|
|
Planet Jupiter |
-has 79 moons -is 5th in the solar system -surface is gas -is the largest planet in the solar system -the planet gives off more heat than it gets from the sun -has a Great Red Spot which is a large hurricane storm -names of the 4 Galilean moons are lo, Europa, Callisto, and Ganymede |

|
Planet saturn |
-has 62 moons -is 6th in the solar system -surface is gas -has a significant ring system -it’s largest moon Titan is a bit bigger than the planet Mercury -the planet is less dense that water (the planet will float if put in water) |
|
|
Planet Uranus |
-has 27 moons -is 7th in the solar system -surface is gas -the planet rotated on its side -was observed many times but wasn’t listed as a planet until 1781 -the planets moons are named after Shakespeare -it has a few faint rings |
|
|
Planet Neptune |
-has 13 moons -is 8th in the solar system -surface is gas -Triton one of its moons has a retrograde orbit -the planet was discovered because of Uranus’s orbital path -the planet has a great dark spot |
|
|
Minor/irrelevant planets |
-has some moons -enough gravity to form into mostly a round shape -made mostly of frozen gasses and dust -most orbit farther from the sun than planet Neptune -they are originally from the Oort cloud |
|
|
Comets |
-Oort cloud objects that get near the sun -made of frozen gas and dust -melt as they get closer to the sun giving off long tails -there tails always point away from the sun |
|
|
Asteroids |
-they are rocks of various sizes -possibly the debris of destroyed planets |
