What is 27 Ursae Majoris

27 Ursae Majoris burns orange about four hundred and seventy-eight light-years away, in the vast constellation of the Great Bear that every northern child learns to find. It is not part of the Plough: it sits aside, in the bear's body, far from the famous asterism. A K-type giant sending aged light from a surface swollen by time and the slow loss of nuclear fuel.
