Artist's impression of a Y-type brown dwarf.

An object with a spectral type Y (also called Y dwarf) is either a brown dwarf or a free-floating planetary-mass object. They have temperatures below around 500 Kelvin (227°C; 440°F) and are colder than T-dwarfs. Y-dwarfs have a similar spectrum when compared to the giant planet Jupiter.
