How Far is Mars?
How far away is Mars? The exact answer varies, of course, as both it and our planet are constantly moving along their own orbits around the Sun. At the time of this writing Mars is on the other side of the Sun from us, 2.413 AU away as the space crow flies (which equates to nearly 361 million km or 224.3 million miles) and, back in 2003, Mars and Earth were at their closest in 50,000 years at a scant 56 million km/33.9 million miles apart. So on average, Mars is about 225 million km/140 million miles from Earth. Give or take a few.
For the sake of convenience, let’s say we reduced Earth to a sphere 100 pixels in diameter and you could travel outward at a velocity of 7,000 pixels/second (which is, to scale, about 3 times light speed) how far would Mars be? Find out here.
