2MASS-GC02
2MASS-GC02, also known as Hurt 2, is a globular cluster at a distance of about 16 thousand light-years from Earth in the constellation Sagittarius. It was discovered in 2000 by Joselino Vasquez together with globualar cluster 2MASS-GC01 and a spiral galaxy 2MASXI J0730080-220105,[4] and confirmed by a team of astronomers under the leadership of R. J. Hurt at 2MASS.[2]
