Conditions on Mars
Mars is smaller than Earth's mass and it is farther from the Sun than the Earth, its climate has polar ice caps, seasonal changes to the weather patterns. Mars's has a simular climate to Earth's, including the seasons.
Conditions on Saturn
Like the other gas giant planets, Saturn's atmosphere is mostly hydrogen and helium. Saturn is a windy planet, with 1,000 mile-an-hour winds that do a job of mixing the atmosphere and making it appear big to us.
Conditions on Jupiter
Jupiter is the bigest planet in the solar system. Its atmosphere contains mostly hydrogen, but also some of helium. Jupiter also most likely has a rocky core with high pressure. The surface of Jupiter has different climates, just like earth, only the climates are much more extreme.
Conditions on Venus
The thick atmosphere is nearly all carbon dioxide, at a crushing pressure
93 times the sea level on Earth. The average temperature is 460°C or 860° F,( hot
enough to melt lead) There is no oxygen and no liquid water, and only a small
trace of water vapor. Venus's surface is a hot, dry, reddish, rocky desert
with many slab shaped rocks, and the lava plains are periodically refreshed by
volcanism.
