Is it possible for brown dwarf stars to support an Earthlike planet?

Answer 1

If by Earth-like you mean temperate, with oceans and atmosphere, probably not. Brown dwarfs have a very brief life as active stars (a million years being "brief" in stellar evolution), after which they slowly cool off. So it's doubtful whether there would be enough heat for enough time to drive the necessary processes. The bigger problem may be tidal locking. I think it works out that a planet in the habitable zone of a brown dwarf has to be so close that it becomes tidally locked to the star - that is, the same side always faces the star. This results in extremes of temperature that would probably strip the planet of most of its atmosphere.

Answer 2

Yes, it would be possible for a brown dwarf star to support the world, but it wouldn't generate enough heat. See, the sun is a star, and all stars die some day. So when the sun has a supernova(explodes), it will turn into a white dwarf like Pluto, but it couldn't support life. But, a few brown dwarfs could. Hope I've helped!!

Answer 3

the brown dwarf can radiate thermal energy and light which plants can use for photosynthesis.But the gravitational pull will be less compared to sun so there are possibilities of earth going away from the orbit around the sun,but if earth is too close to the star there will be too much of radiation and it wont support the life forms.

Answer 4

It could support an earth sized planet in orbit but there wouldn't be much heat to produce a planet like earth.

Answer 5

Lol with that good judgment I wager there is a few alien planet someplace who observed our planet in a telescope and pronounced "sounds like yet another uninhabitable rock, that place is a lot too warm for us." My element is that if existence can exist, that's going to exist, and the barriers asserting the place it may and can't exist are artifical, no longer surely reality.
