 __Red Giant__

__Definition:__ Red Giants are starts with radii ten to hundreds larger then our sun alltogether.

__How they are formed?__ The colour of which the red giant looks like is yellow orange to red, they say that our sun in 5 billion years for now will become a red giant like the one in the picture. The most common of the red giants that we see or most of them called the red giant branch, known as [RGB]. Our sun will run out of hydrogen in the core which will then cause it to use the hydrogen in the outer shell which will cause it to expand into the inner four plannets and completely destroy us.

 __What happens when the core runs out?__ When the star runs out of hydrogen in its core, nuclear reactions in the core stop, so the core begins to contract due to its gravity.
