At 2.312 Earth masses, GJ 3323 c is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. With a mass below 5 Earth masses, and a semi-major axis of 0.1264 astronomical units, which is outside the habitable zone of GJ 3323, GJ 3323 c is likely an icy world.
