Which would you rather live on? Mars or Venus?
A comparison of the planets Mars and Venus to Earth.

To start with, Earth has an axial tilt of 23.4°, Mars 25°, and Venus 178°. The axial tilt determines the possibility of seasons. Mars' axial tilt is very similar to Earth's but Venus' axial tilt is way out there.
The length of day on Mars is 1.026 Earth days (or about 24 hours and 39 minutes). The length of day on the planet Venus is 243.02 Earth days and Venus rotates in the opposite direction of both Earth and Mars.
The length of year on Mars is about twice as long as on Earth though, 686.98 Earth days. The length of year on Venus is 224.7 Earth days, which is 18.3 Earth days shorter than its own day.
The mean average temperature on Earth is positive 46.1°F, on Mars it is negative 45.7°F, and on Venus it is positive 847°F. Making Mars frigid and Venus a furnace. Perhaps food could be cooked on Venus and sent for storage on Mars... ![]()
