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 Hottest planet in
solar system
Venus
The atmosphere of Venus contains a high percentage of carbon dioxide that holds heat in the planet's atmosphere.
The atmosphere of Venus is made of thick clouds of sulfuric acid and carbon dioxide, which makes it very hot.
Earth
Home sweet home Only planet with
sustained life Hydrosphere
(water) Atmosphere made
up of N, O, CO2 Comfy temps
Earth
Earth has fewer craters than other terrestrial planets because of its atmosphere (upper) which destroys meteorites.
Mars
Frozen polar CO2 caps
Smaller than Earth Slightly longer day
and year Very cold Largest mountain
in solar system Olympus Mons
Thin atmosphere
Asteroid Belt
Separates the inner and outer planets
Possibly an annihilated planet
Most asteroids hang out here
Outer Planets
Gas giants No solid surface, just thick
atmosphere All very large Very far apart from each other All have rings
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
Jupiter is largest planet in the solar system.
Jupiter can fit all of the other planets inside this gas giant and there would still be space left over.
Saturn
29 years to orbit Large rings made
of ice and dust 10 hour day Possibly still
forming Tilts itself
Saturn
Saturn is known for its’ rings and is the least dense planet. It would float in a swimming pool if we had one big enough to put this planet into.
