SMALLEST STAR IN THE GALAXY

 The smallest known star in the galaxy is a type of star called a red dwarf, which is a type of low-mass star that is smaller and cooler than other types of stars. These stars are usually only a few times the mass of Jupiter, which is much smaller than the Sun, which has a mass of about 330,000 times that of Jupiter.

Red dwarfs are the most common type of star in the Milky Way galaxy, and they are thought to make up about 70% of all stars in the universe. They are much cooler and dimmer than other types of stars, and many of them are too faint to be seen with the naked eye.

Despite their small size and low luminosity, red dwarfs can live for billions of years, much longer than larger and more massive stars like the Sun. They are also relatively stable and do not experience the explosive events such as supernovae that can mark the end of a larger star's life.

Overall, red dwarfs are some of the smallest and longest-lived stars in the galaxy, and they play a crucial role in the evolution and structure of the Milky Way and other galaxies.
