Class of stars Blue Giant
The nearest black holes are collapsed massive stars scattered across our Galaxy. The closest known is Gaia BH1, located 1,560 light-years away. If our Solar System were scaled down to the size of a coin, this black hole would still be hundreds of kilometers away. Black holes do not act as cosmic vacuum cleaners; if our Sun were replaced by a black hole of equal mass, the planets would continue orbiting in exactly the same paths, though without light or heat. A black hole's gravity is extreme only very close to its event horizon. Thus, despite millions of stellar black holes residing in the Milky Way, the nearest ones pose no danger to Earth.

More about Star mass in StellarGuide
Data in Stellar Catalog come from trusted scientific sources. Primary source is Gaia space telescope mapping the stars in Milky Way. Other sources include research papers, Simbad catalog and Exoplanet.eu database.
Objects listed in the Stellar Catalog often have values that are estimates. These estimates are determined using their known characteristics, such as spectral type, brightness across different wavelengths, distance from a star, and other factors.
Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
