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.
