At first glance this seems like it should be an easy question to answer because Mars is usually about 225,000,000 km away from the sun as it orbits. But to figure out how far away Earth is from Mars isn't as easy. We are both orbiting the Sun, Earth closer than Mars, and both planets orbit at different speeds, so we never remain at the same distance from each other. At her closest Mars came about 59,000,000 km from Earth. Usually she is about 100,000,000 km away. But when they are each on opposite sides of the sun, they can be about 400,000,000 km apart.

Mars is Cold! Windy and cold, with winter temperatures at the poles going as low as -125/-195 degrees Celsius/Fahrenheit. Just like Earth, Mars is at a tilt to the sun, and her orbit is elliptical, both of which create distinct seasonal variations in temperature and weather patterns. The day to land on Mars to do some sightseeing would be midsummer, at noon, on the equator where you might find a balmy temperature of 20/70 degrees C/F, quite comfortable really. But that wouldn't last long and the typical temperatures of -25/-13 degrees C/F would soon be upon you. I'm thinking you could consider the usual temperature anywhere on Mars to be at least as cold as the coldest day of winter at the North Pole on Earth, and then probably colder than that still. And don't get caught out in one of those polar freezes, I'm pretty sure your blood would freeze solid in seconds.
