How do astronomers name new celestial bodies?

New celestial bodies, such as exoplanets, asteroids, and comets, are named following a standardized process established by the International Astronomical Union (IAU).

Once approved, the name is officially adopted and recognized by the astronomical community.

It is one of the nearest stars to Earth, located at a distance of approximately 36.7 light-years. Its discovery and study have provided valuable insights into stellar evolution and the properties of red giants.
