How big is Betelgeuse compared to the sun?

Answer

According to NASA, Betelgeuse is a supergiant star that is more than 1,000 times larger than the sun. Thanks to its mighty heft, Betelgeuse is 7,500 times brighter and has 20 times the mass of the sun.

Considering how very large Betelgeuse is, Earth's inhabitants are quite lucky to orbit around a star that's as comparatively dainty as the sun. Betelgeuse is one of the largest-known stars, and it is about 700 million miles in diameter. According to the National Radio Astronomy Observatory, a federally funded research center, one way to consider the size of Betelgeuse is to compare it to Jupiter's orbit around the sun. That means that if Betelgeuse suddenly replaced the sun, the Earth's solar system would be in big trouble.

Another difference between Betelgeuse and the sun is in the colors of the two stars. As anyone on Earth can see, the sun is a yellow-orange color, but Betelgeuse is an orange-red color. This star's huge size and different coloring can be attributed to its maturity; it is an evolved star, a red supergiant that may have been even larger at an earlier point in its development. Betelgeuse is part of the constellation of Orion, and though it is one of the largest known stars, it is not the largest. That honor, as of June 2014, belongs to Eta Carinae, which is 150 times larger than the sun.
