      Not enough mass to go supernova; the sun is expected to become a red dwarf.

        White dwarf

        Red dwarves are failed stars that never attained the mass necessary to become a full-on star. Jupiter actually isn’t far off from this status.

        On a related note, red dwarves will probably be some of the last sources of light in the universe, and live for trillions of years due to how slowly they burn fuel, so… suck it, Shapiro?

          You might be thinking of brown dwarfs. Red dwarfs are fully qualified stars which sustain nuclear fusion in their cores. Brown dwarfs do not, though still emit radiation by other various means.

          Jupiter is also somewhat close, in astronomical terms, to being a brown dwarf. It is not even remotely near being a red dwarf.

          Your last point is correct though. Red dwarfs last much, much longer than all other stars due to being fully convective which allows them to consume all their fuel uniformly.

          Jupiter’s quite a long way off from being a red dwarf it would need to be in any 10 times the mass be a red dwarf.

          Jupiter is somewhat close to being a brown dwarf which is a star that failed to even become a failed star and is merely hot and glowy but not plasma. Jupiter’s atmosphere is just gaseous though perhaps really deep down at the core it achieves brown dwarf level status but we don’t consider it to count because it’s not the whole planet.
