K2-296b (more commonly referred to as EPIC 201238110 b) is a potentially habitable[3] planet discovered by Heller et al.[5] in 2019, orbiting the M-dwarf star[6] EPIC 201238110.

Habitability

K2-296b's orbit, which has a semi-major axis of 0.135 AU (20,200,000 km),[3] is located in the habitable zone of the planetary system, meaning liquid water could exist on its surface.[6] Its equilibrium temperature is estimated at 277 K (4 °C; 39 °F).[3] The planet is likely tidally locked to its parent star.[6] The Habitable Worlds Catalog, issued by the Planetary Habitability Laboratory, classes the planet as a warm superterran, near the inner edge of the optimistic habitable zone.[3]

Host star

The host star, EPIC 201238110, is a red dwarf with a mass of 0.41 M☉[6] and a radius of 0.37 R☉.[3] It has a surface temperature of 3588 K[7] or 3772 K,[3] and a luminosity of 0.0254 L☉.[3] There is another transiting[5] candidate planet in the system called EPIC 201238110 c, which, if confirmed, would be a hot (427 K) mini-Neptune with a radius of 2.76 R🜨 and a mass of 8.0 ME, revolving around the star once every 7.9 days at a distance of 0.058 AU (8,700,000 km).[3]
