HD 202628 [SEP] constellation
HD 202628
HD 202628 is a G-type star in the constellation Microscopium with an elliptical (e=0.18) dust disc, inclined at 64°. The inner edge of the ring, which lies at around 158 AU from the star, is sharply defined. This means that there is a likely planet responsible for this defined edge, and it has been calculated as orbiting between 86 and 158 AU from HD 202628.
8 light-years distant. It passed within 1.14 and 3.45 light-years of the Sun some 3.9 million years ago, possibly disturbing the outer Solar System. Two star systems—WASP-7 and HD 205739—have been determined to have planets, while two others—the young red dwarf star AU Microscopii and the sunlike HD 202628—have debris disks. AU Microscopii and the binary red dwarf system AT Microscopii are probably a wide triple system and members of the Beta Pictoris moving group. Nicknamed "Speedy Mic", BO Microscopii
