Rho-2

Its story

Rho-2 Sagittarii is an orange K-type giant lying some 332 light-years away, in the Archer, the constellation that points toward the very centre of our galaxy. It is a sun that has left its youth behind and swollen into a warm, ruddy beacon, one of many that populate one of the densest regions of the sky, just where the Milky Way blazes most strongly for the summer observer.
