Teide 1 is a brown dwarf located around 430 light years away in the Pleiades. It was the first brown dwarf to be confirmed. Its surface temperature is 2,600 ± 150 K, which is about half that of the Sun. Its luminosity is 0.08–0.05% of that of the Sun. It is estimated to have about the same age as Pleiades, giving a plausible range from 70 to 140 Myr.
