Apart from the Sun, it's the closest star system to us. The whole system consists of three stars, Alpha, Beta and Proxima Centauri. If we ever developed technology to travel between stars, it would be the logical first place to visit. Not if there's nothing there, which appears to be the case. ID: 551205 ·

At about 25,000,000,000,000 miles away appearances can be deceptive, I'll be witholding judgement on this until after we get the results back from the first few missions there!
