Terrestrial High temperatures Closer to the Sun Closer to each other Closest to the Sun Only 88 days to orbit Many craters Temperature extremes • 400C during day, -180 at night Basically no atmosphere Earth’s sister planet Morning and evening star Thick atmosphere of CO2 and Sulfur Longer day than year Spins opposite than other planets Over 500C all the time Home sweet home Only planet with sustained life Hydrosphere (water) Atmosphere made up of N, O, CO2 Comfy temps Frozen polar CO2 caps Smaller than Earth Slightly longer day and year Very cold Largest mountain in solar system • Olympus Mons Thin atmosphere Separates the inner and outer planets Possibly an annihilated planet Most asteroids hang out here Gas giants No solid surface, just thick atmosphere All very large Very far apart from each other All have rings Could hold 1300 Earths Almost big enough to be a star 12 EY = 1 Jovian year 1 Jovian day = 12 EH Huge storms Great red spot “hurricane” larger than Earth Some moons may have water 29 years to orbit Large rings made of ice and dust 10 hour day Possibly still forming Tilts itself Blue in color due to methane gas 84 years to orbit Rotates sideways Very cold • -250C Methane atomosphere 164 years to orbit -250c temps 30 times farther from the sun than Earth
