At 3.975 Earth masses, OGLE-2018-BLG-0677L 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 0.63 astronomical units, which is outside the habitable zone of OGLE-2018-BLG-0677L, OGLE-2018-BLG-0677L b is likely an icy world.
