GJ 251 Archives

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

Discovery Of A Nearby Habitable Zone Super-Earth Candidate Amenable To Direct Imaging

by Keith CowingOctober 28, 2025October 29, 2025

We present the discovery of GJ 251 c, a candidate super-Earth orbiting in the Habitable Zone (HZ) of its M dwarf host star.

An international team of scientists, including researchers at Penn State, dubbed the exoplanet, named GJ 251 c, a “super-Earth” as data suggest it has a rocky composition similar to Earth and is almost four times as massive.
