Mercury • Closest to the Sun • Only 88 days to orbit • Many craters • Temperature extremes • 400C during day, -180 at night • Basically no atmosphere
Venus • 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
Earth • Home sweet home • Only planet with sustained life • Hydrosphere (water) • Atmosphere made up of N, O, CO2 • Comfy temps
Mars • Frozen polar CO2 caps • Smaller than Earth • Slightly longer day and year • Very cold • Largest mountain in solar system • Olympus Mons • Thin atmosphere
Jupiter • 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
Saturn • 29 years to orbit • Large rings made of ice and dust • 10 hour day • Possibly still forming • Tilts itself
Uranus • Blue in color due to methane gas • 84 years to orbit • Rotates sideways • Very cold • -250C
Neptune • Methane atomosphere • 164 years to orbit • -250c temps • 30 times farther from the sun than Earth
