WD 0806-661 B, formally named Ahra, is a planetary-mass companion of the white dwarf star WD 0806−661, or Maru. This object was discovered in 2011 by the Spitzer Space Telescope. It has a mass of between 7-9 MJ, putting it as a gas giant planet. At the time of its discovery, WD 0806-661 b was the coldest brown dwarf ever discovered, with a temperature of 325-350 Kelvin (52-77 °C or 125-170 °F) and also had the largest separation from its star at about 2,500 AU at the time of its discovery. The photometric colors of the object suggest it is metal-poor.
