WebAnswer (1 of 7): Humans have defined the term “star” such that fusion as a necessary requirement for qualifying as one. Thus, from a purely banal semantic point of view, no. … WebStars can easily fuse atoms to give of heat and radiation. But at Wikipedia it said that only sub-iron atoms give of energy when fused and take energy when split, and post-iron atoms is the exact opposite. So, if enough heavy elements got together could a "reverse star" be made in which it gives of light and heat through means of fission?
