The largest type of star by diameter is the red supergiant. These stars are massive and have a diameter of over 1,000 times that of the Sun. One example of a red supergiant is Betelgeuse, which is located in the constellation Orion.

Red supergiants are formed when a star runs out of hydrogen fuel in its core and begins to expand, becoming cooler and redder in the process. These stars are rare, making up less than 1% of all stars in the universe, but they play a significant role in the life cycle of stars.
