Gaia BH3 is located 1926 light years away (590.6±5.8 pc away) in the constellation of Aquila.

[2] Gaia BH3 was found to be part of a disrupted star cluster of low mass and this star cluster is today a halo stellar stream, called ED-2.

This stellar stream is very old, with an age comparable to the globular cluster Messier 92.

Alternatively the black hole could have formed via binary interaction inside the star cluster.

It was announced with the publication of a scientific paper in the journal Astronomy & Astrophysics on 16 April 2024.
