The measured figure, for a body that is not a spheroid. See BodyFigure.

mass: number
measurementreadonly
How the mass and radius were arrived at, for an observed body. Radial
velocity gives M sin i — a lower bound, not a mass — and a transit gives a
radius with no mass at all, so one of the two is very often inferred from
the other. The panel says which.

Polar radius. Smaller than radius for anything that spins.
Not a detail: Saturn is 9.8% flattened and Jupiter 6.5%, which is plainly visible from orbit and is the first thing that reads as wrong when a gas giant is drawn as a sphere. It is also real physics — centrifugal support against self-gravity — so procedural bodies get it too, from their own rotation and mass.
