Astronomy:Potato radius
From HandWiki
The potato radius is the size at which an asteroid is massive[1] enough that gravity begins to make it rounder.[2] The potato radius defines hydrostatic equilibrium and is used to separate dwarf planets from small Solar System bodies.[3][4] Charles Lineweaver and Marc Norman at the Australian National University in Canberra first proposed an objective definition of a planet that separates potato-like objects from spherical ones.[5][6][7]
