HD 19467 B[1] (also stylized as HD 19467 b[2]) is a brown dwarf orbiting around the Sun-like star, HD 19467 approximately 101 light-years away in the constellation of Eridanus. It has a surface temperature of 978.0 K (704.9 °C; 1,300.7 °F),[2] and is classified as a T5.5.[1] While considered a brown dwarf rather than a planet, it is included in the Extrasolar Planets Encyclopaedia due to its mass being below their upper limit of 60 Jupiter masses.[2]
