The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are an average of 4.3 light-years from Earth. Lots of people dont know most stars have a 'sister' star. Our star aka the sun is a rare star that has lost its binary partner. With our rockets it would take about 76,000 years to get there but if you are like me you know they have UFO tech out there to go faster :)
