Definition

A feature termed planum is a topographically high-standing plain or plateau. These features are found on the terrestrial planets Mercury, Venus, Moon, and Mars, on Jupiter’s satellite Io, and on Neptune’s satellite Triton. The spatial extent (diameter) of a planum is a few hundred kilometers up to approximately 2,400 km (Lakshmi Planum, Venus). High-standing plains were created by (cryo-)volcanism and/or tectonism.
