Gaia BH2 is the second black hole discovered from Gaia DR3 astrometric data. [3] The black hole and red giant orbit the system barycentre every 1,277 days, or around 3.5 years, with a moderate eccentricity of 0.518. The black hole's mass is around 8.94 M ☉, which means its Schwarzschild radius should be about 26.4

The black hole and star orbit the system barycentre every 11.6 years, with an orbital distance ranging from 4.5–29 AU. [3] The black hole's mass is 32.70 M ☉, the heaviest known stellar black hole in the Milky Way. The black hole Gaia BH3 is the second known stellar black hole more massive than about 10 M ☉ (with the first being Cygnus X-1).
Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years. Even more astounding to scientists, this black hole is a whopper — 10 times bigger than ...
The Black Hole is a 1979 American science fiction film directed by Gary Nelson and produced by Walt Disney Productions.The film stars Maximilian Schell, Robert Forster, Joseph Bottoms, Yvette Mimieux, Anthony Perkins and Ernest Borgnine, while the voices of the main robot characters are provided by Roddy McDowall and Slim Pickens (both uncredited).
The star is moving so fast that it can complete an orbit 2.5 times the distance between our Earth and the moon in just half an hour.
