The brightest star in the Orion constellation, Rigel is 9000º F hotter than our own sun. It is a blue super giant.
Rigel is a B8 class star which means it is very large, very hot and very young by comparison to other stars. It is virtualy impossible to age a specific star. This is usually done by aging star clusters, a much more accurate method. Rigel is estimated as being 17 times as heavy as the sun and thro…

Both Betelgeuse and Rigel are listed as being only 10 million yeas old, compared to the sun's 4.5 billion. Both are also expected to supernova soon, though Betelgeuse is expected to go out sooner, as it's been anticipated since 2011.

Stars are made up of the same elements as Earth, but in different proportions. In general, stars are made up mainly of hydrogen, less helium, while the so-called "metals" (i.e., any heavier elements) make up a small portion of the star. Older stars may have more "metals".
