Red giant

A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M☉)) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius immense and the surface temperature low, from 5,000 K and lower. The appearance of the red giant is from yellow-orange to red, including the spe...

Red Giant

A very large, distended, and relatively cool star which is in the final stages of its life. A typical red giant, if placed where the Sun is in our solar system, might extend past the orbit of Mars. The relatively cool temperature of its outer layers (perhaps only 2,000 degrees Celsius as compared to the Sun's 6,000 degrees) would make it look orang...

Red Giant

A stage in the evolution of a star when the fuel begins to exhaust and the star expands to about fifty times its normal size. The temperature cools, which gives the star a reddish appearance.

Red Giant

An old star that has used up all the hydrogen in its nucleus and uses other elements as fuel to keep shining. The Sun will become a red giant in the future. These stars can be 25 times as big as the Sun, and hundreds of times brighter.

red giant

Any large bright star with a cool surface. It is thought to represent a late stage in the evolution of a star like the Sun, as it runs out of hydrogen fuel at its centre and begins to burn heavier elements, such as helium, carbon, and silicon. Because of more complex nuclear reactions that then occur in the red giant's interior, it eventually b...
