A brown dwarf is a failed star. A wannabe. It’s a ball of gas that never quite made it. Professor Michio Kaku
A brown dwarf is basically a failed star ... very low temperature, and so they emit very very little light. Because they are so dim it means we can only see them if they are really close to us. If something is born with less than 8% of the mass of the sun, then it can’t produce its own energy; it’s essentially a failed star. Michael Liu, University of Hawaii
Throughout the universe failed stars called Brown Dwarfs hide in the shadows. While they are more massive than our largest planet Jupiter they are so faint that telescopes find it difficult to detect them. Despite being a failure for a star, temperatures on brown dwarfs are still pretty impressive. At over 3,000° Fahrenheit. And unlike stars that are too hot to have weather, brown dwarfs have cooled enough to experience convection and condensation. At these temperatures rain takes on a whole new terrifying meaning.

In 2011 one of Nasa’s space telescopes, the Wide-Field Infra-Red Survey Explorer [WISE] ... found a series of Brown Dwarfs right in our neighbourhood. The Universe s7e3: Our Place in the Milky Way
