Fact of the Day: Mars and Earth


Although it is much colder on Mars than on Earth, the similar tilt of Earth's and Mars' axes means they have similar seasons. Like Earth's, Mars' north and south polar caps shrink in the summer and grow in the winter. In addition, a day on Mars is 24 hours 37 minutes - nearly the same as Earth's. No other planet shares such similar characteristics with Earth.
