Teide 1
Brown dwarf in the constellation Taurus / From Wikipedia, the free encyclopedia
For the volcano in Tenerife, see Teide.
Teide 1 is a brown dwarf located around 430 light years away in the Pleiades. It was the first brown dwarf to be verified, in 1995.[6] Its surface temperature is 2,600 ± 150 K,[7] which is about half that of the Sun. Its luminosity is 0.08–0.05% of that of the Sun.[8] It is estimated to have about the same age as Pleiades, giving a plausible range from 70 to 140 Myr.[8]
