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, and confirmed by a team of astronomers under the leadership of R. J. Hurt at 2MASS.[2]

The globular cluster 2MASS-GC02 is not in the visible portion of the electromagnetic spectrum, due to interstellar extinction, but was spotted in infrared light. It is located at a distance of 10.4 thousand light years from the center of the Milky Way.[2]
