RELIEF_RADIUS_FRACTION

The most of its own radius a body carries as relief.

Vesta again, and it is the extreme: 22 km on a 262 km mean radius is 8.4%. The bound exists because the strength limit is useless on a small body — a 50 km moon could hold a 5,000 km mountain by that arithmetic — and something has to say that a body may not be mostly mountain.
