Mars has a 24-hour day. It has polar ice caps. Its axis is tilted compared with its orbit, just as Earth is tilted on its axis. That means Mars goes through seasons, just like Earth. Mars, as cold as it is, is not as oppressive an environment as almost any other place we can think of going in the Solar System. From a runaway greenhouse effect, Venus is 900 degrees Fahrenheit and would melt or vaporize most things you sent to its surface. Mercury is also very hot, being close to the Sun.
Distance from the sun: 128,409,598 to 154,865,853 miles (206,655,215 to 249,232,432 km)
Length of space journey from Earth: 3 years
