If you add a little more than 80x it’s existing mass it will then become a low-mass star. But why ruin a good sci- fy movie.It would be incredibly cold there. Now if Jupiter were to become a star it would be much differant. Scientist are saying it's almost there. A bit more mass and boom! We become a binary system.
Science suggests in order to become a Brown Dwarf, you would need approximately 13x the current mass of Jupiter. In order to become a Red Dwarf star, you would need 80x Jupiter masses.It could always become a dwarf star. We don't know.
It’s called yellow because of its spectral type, but this is a bit of a long story about how a pure white star got saddled with yellow.Ours is a yellow star would it be the same ?
