How do spaceships and space labs not run out of fuel (energy) like going to mars and landing and then sending pictures? Moreover, the equilibrium temperature of Proxima b is estimated to be within the range where water could exist as liquid on its surface; thus, placing it within the habitable zone of Proxima Centauri. This is slightly greater than the distance between Uranus and t… Join Yahoo Answers and get 100 points today. So it would be 4.3 (it's actually 4.22 light years by the way) times the length of a light year in km. A light-year is the distance that light travels in one year (365 days).

If you mean "other than the Sun", that would be Proxima Centauri, at a distance of about 4.2 light-years.150 million kilometers. 1 light-year = 9.460536x10^15 m, so you can figure it out for yourself.
