The size of GJ 251 and the orbits of GJ 251 b and c. Stellar size and orbital distances are to scale. In light green we show the optimistic HZ, and in dark green the conservative HZ (Kopparapu et al. 2013, 2014). GJ 251 c orbits directly in a regime where liquid water might be able to exist on its surface. -- astro-ph.EP
