A0620-00 (V616 Monocerotis, V616 Mon) is a low-mass X-ray binary star and black-hole candidate in the constellation of Monoceros.[1][2]

Evidence from observation

One of the components of the A0620-00 binary system is known to be a dark, compact stellar object, with a mass between 6.3 and 6.9 times the mass of the Sun. The other component is observed to be a K-type star (approximately 0.5 solar masses).[3][4][5][6]

Significance

This binary system is located at a distance of approximately 3,000 light years, making the system the likely location of the nearest known black hole.[7]
