At 1.972 Earth masses, PSR B0329+54 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 10.26 astronomical units, which is outside the habitable zone of PSR B0329+54, PSR B0329+54 b is likely an icy world.
