AU Microscopii is a red dwarf star located 10 parsecs away about 8 times as far as our closest star after the Sun. AU Mic is a young star, only 12 million years old, less than 1% of the age of the Sun. It has only half the mass of the Sun and is only one-tenth as bright. The star was given this name because it is in the constellation Microscopium and is a variable star. AU Microscopii is a member of the Pictoris moving group. AU Microscopii may be bound to the binary star AT Microscopii. Like Pictoris, AU Microscopii has a circumstellar dust disk known as a debris disk.
