HR 2562 B is a substellar companion orbiting the star HR 2562. Discovered in 2016 by a team led by Quinn M. Konopacky by direct imaging, HR 2562 B orbits within the inner edge of HR 2562's circumstellar disc—as of April 2023, it is one of only two known brown dwarfs to do so.[2] Separated by roughly 20 astronomical units (3.0×109 km) from its primary companion, HR 2562 B has drawn interest for its potential dynamical interactions with the outer circumstellar disc.
