At 2.811 Earth masses, KMT-2021-BLG-0912L b 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 3.14 astronomical units, which is outside the habitable zone of KMT-2021-BLG-0912L, KMT-2021-BLG-0912L b is likely an icy world.
