How many miles away is the nearest star to mars?
The closest star to Mars is the Sun. The distance of Mars to the Sun is 227.92 million km or 141.62 million miles. However, Mars orbits the sun in an elliptical orbit, so at its closest point called the perihelion, it is only 206.62 million km away, or 128.39 million miles. At its farthest point, Mars is 249.23 million km away, or 154.86 million miles.

Can the human race live somewhere else in the mikyway?
Yes it IS possible.There are over 200 billion stars to choose from. There must be a suitable planet orbiting one of those stars.The BIG problem is getting to them.Our nearest star system, Alpha Centauri is 4.2 light years away. (Unfortunately, to date no planets have been found around them).Our fastest craft, Voyager 2 is travelling at about 35,000 mph. If it was to make it to Alpha Centauri, it would take ..... about 80,500 years!!!
