Sol, a yellow dwarf, in 2286.

A yellow dwarf is a type of star which is undergoing hydrogen-helium conversion, relatively small in size, glowing with a yellow light. Yellow dwarves typically have a life-span of around 10 billion years and later expand into a red giant when the internal supply of hydrogen has been exhausted. (ST reference: Star Charts)
