From research I have fund out that Alpha centauri is a binary star system and some people think that it should be a triple system with the star proxima centauri in it.
Alpha Centuari is 4.4 light years away. We are talking about 44 trillion km (44,000,000,000,000 km) away. its actually is more like 42,479,700,000,000 kilometers away if you want it exact Alpha...
