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 globular cluster 2MASS-GC01 and a spiral galaxy 2MASXI J0730080-220105,{{sfn|Hurt|Jarrett|Kirkpatrick|Cutri|2000}} and confirmed by a team of astronomers under the leadership of R. J. Hurt at 2MASS.

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. Due to its trajectory, it has a negative radial velocity meaning it is approaching the Solar System, but its radial velocity is unclear. The radial velocity was originally put at −238 km/s,{{cite journal|doi=10.1093/mnras/sty2997|title=Mean proper motions, space orbits, and velocity dispersion profiles of Galactic globular clusters derived from Gaia DR2 data|year=2019|last1=Baumgardt|first1=H.|last2=Hilker|first2=M.|last3=Sollima|first3=A.|last4=Bellini|first4=A.|journal=Monthly Notices of the Royal Astronomical Society|volume=482|issue=4|pages=5138–5155|doi-access=free |arxiv=1811.01507}} but a newer analysis determined it to be −87 km/s; a 150 km/s difference.{{cite journal|doi=10.3847/1538-3881/ac0888|title=Spectroscopic Observations of Obscured Populations in the Inner Galaxy: 2MASS-GC02, Terzan 4, and the 200 km s⁻¹ stellar peak|year=2021|last1=Kunder|first1=Andrea|last2=Crabb|first2=Riley E.|last3=Debattista|first3=Victor P.|last4=Koch-Hansen|first4=Andreas J.|last5=Huhmann|first5=Brianna M.|journal=The Astronomical Journal|volume=162|issue=3|page=86|arxiv=2106.02647|bibcode=2021AJ....162...86K|s2cid=235358083 |doi-access=free }}
