BBC : A binary system of stars is common. A triplet system is less so. A quintuplet system is extremely rare. Nevertheless, two five-star systems have been found so far, the second one just 250 light-years from Earth. Marcus Lohr of the Open University in the UK and his colleagues found the system in data collected by the Super Wide Angle Search for Planets project. The stars are arranged as two binary pairs, one of which also has a single companion star. The other pair of stars are so close together that they share the same atmosphere. Both groups of stars orbit around a mutual center of gravity.
