Gliese 3483 System

A star system containing a white dwarf 62% as massive as the sun. A planet or brown dwarf has been visually detected in a distant orbit. It is too small (6-10 Jupiter masses) to likely be a brown dwarf, but may be too far out (2,500 AU) to have formed like a planet (would have been 700 AU before star expanded).

Possible Planet or Brown Dwarf
