Which star is closest to us?

The closest star to us is actually our very own Sun at 93,000,000 miles (150,000,000 km). The next closest star is Proxima Centauri. It lies at a distance of about 4.3 light-years or about 25,300,000,000,000 miles (about 39,900,000,000,000 kilometers). A car travelling at a speed of 60 miles per hour would take more than 48 million years to reach this closest star. Proxima Centauri is actually part of a triple star system which also includes the stars Alpha Centauri A and B. It is a small, red star which is about one tenth the size of our Sun.
