AU Microscopii is also known as Gl 803, HD 197481, and CD-31°17815. It forms a triple star system with the double red dwarf star AT MiC, located 1.2 ly away, which are also known as Gl 799, HD 196982, and CD-31°16135. An active flare star and about 12 Million Years old. First red dwarf found with a circumstellar disk and the nearest planetforming disk. Also the first system where particle size in disk determined. Constraints on where planets could exist was recently published. Patterns in the dust disks suggest planets. It is thought that Pluto-sized planetoids may have formed in the outer system. AT MiC A and B are separated by 24.2 to 40.8 AU, and are somewhat smaller than AU MiC. All components are part of the Beta Pictoris Moving Group.
