What is the nearest star to us beside our sun and what is the distance?

The closest known star is Proxima Centauri, a red dwarf star that has a mass of about 10 percent of the Sun. It's distance from us is 4.2 light years. It's a distant companion to Alpha Centauri, which is double star 4.3 light years away. This double star consists of a Sun like yellow main-sequence or hydrogen fusing star and a slightly smaller, fainter and cooler orange companion that circle each other in a period of 80 years with an average separation of about 2 billion miles. Proxima Centauri in turn orbits the bright pair of stars at a distance of nearly 1,000,000,000,000 miles, or a sixth of a light year. It takes a million years or more to circle Alpha Centauri A and B. Because it's on the near side of the Alpha Centauri system, it was given the name Proxima Centauri.

Proxima Centauri is the nearest to us (other than our Sun) and it is 4.23 Light Years away from Earth.

alpha centauri and its about 4.23 light years away. with our current space shuttles it would take about 75,000 years to reach.
