Objects with masses less than 0.08 solar masses are failed stars called brown dwarfs. Due to the low temperature, thermonuclear reactions cannot begin in them. Under the influence of gravitational forces, they slowly contract and, due to this, radiate in the infrared region. The planet Jupiter can be considered a brown dwarf, since it emits more energy than it receives from the Sun.
