This is a list of known black holes that are close to the Solar System. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [1] Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more
The star and black hole orbit each other with a period of 185.59 days and an eccentricity of 0.45. The star is similar to the Sun , with about 0.93 M ☉ and 0.99 R ☉ , and a temperature of about 5,850 K (5,580 °C ; 10,070 °F ), while the black hole has a mass of about 9.62 M ☉ . [ 3 ]
The black hole has been observed in the star cluster called Omega Centauri – a collection of around 10 million stars. Astronomers find nearest massive black hole – study Skip to main content
At a distance of roughly 3,300 light-years (1,000 parsecs) away, the black hole of A0620-00 would be one of the nearest known black holes to the Solar System, closer than GRO J1655-40. [10] This image of A0620-00 was created from Sloan Digital Sky Survey data in visible and infrared light (filters u,g,i,z) and spans roughly 8 arcminutes.

The Earth’s closest black hole isn’t a black hole at all. Instead, astronomers say it’s just a two-star system where one star is sucking the life out of the other. Earth’s closest black ...
At the time, it was considered to be the closest known black hole to Earth, at a distance of approximately 1,600 light-years (490 pc). Later observations showed it to be much farther away, reported in 2001 to be between 7.4 and 12.31 kpc , [ 7 ] 6.2 kpc in 2014, [ 4 ] and around 6.6 kpc according to its Gaia Data Release 2 parallax.
Astronomers suspected the NGC 7727 galaxy hosted the two black holes, but had not been able to confirm their presence until now. Astronomers uncover closest pair of supermassive black holes yet ...
