Red giant



A red giant is a process in which a star is nearing the end of its life. The star going red giant will swell in size, as they burn heavier elements after the hydrogen depleted. Sometime after the red giant grows, it becames critical, causing the star to go supernova.

Our sun will go red giant in around 5,000,000,000 years time. The star that M35-117 orbits will go red giant in 48,000 years time. However, in one of the alternate realities Sheppard's team visited, the star went red giant too early.
