Mammoth stars vs little blue star size comparison

As you probably can guess, our Sun is an average star. Stars can be bigger than the Sun, and stars can be smaller. Let's take a look at the size of stars.




The smallest stars out there are the tiny red dwarfs. These are stars with no more than 50% the mass of the Sun, and they can have as little as 7.5% the mass of the Sun. This is the minimum mass you need for a star to be able to support nuclear fusion in its core

Star Classification

The Sun is a as a G2V type star, a yellow dwarf and a main sequence star.
Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.

O and B stars are uncommon but very bright; M stars are common but dim..

An easy mnemonic for remembering these is: "Oh be a fine girl, kiss me."
