A blanet is a member of a hypothetical class of exoplanets that directly orbit black holes.
[1] Blanets are fundamentally similar to other planets; they have enough mass to be rounded by their own gravity, but are not massive enough to start thermonuclear fusion and become stars.
In 2019, a team of astronomers and exoplanetologists showed that there is a safe zone around a supermassive black hole that could harbor thousands of blanets in orbit around it.
[2][3] The team led by Keiichi Wada of Kagoshima University in Japan has given this name to black hole planets.
Blanets are suspected to form in the accretion disk that orbits a sufficiently large black hole.
