Types of Stars The universe’s stars range in brightness, size, color, and behavior. Some types change into others very quickly, while others stay relatively unchanged over trillions of years. Main Sequence Stars A normal star forms from a clump of dust and gas in a stellar nursery.
Types of Stars | Stellar Classification, Lifecycle, and Charts
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B are uncommon, very hot and bright. M stars are more common, cooler, and dim. The video below presents a helpful overview of the types of stars in the Universe.
