The Potato Radius: a Lower Minimum Size for Dwarf Planets

WebbThe point at which a celestial object collapses into a sphere is the "Potato Radius" - source What celestial objects can a meteoroid come from? The first human made object to ever touch another celestial object was a metal sphere with an explosive designed to scatter Soviet insignia across the lunar surface on impact, carried aboard Luna 2 in 1959. The potato is a starchy food, a tuber of the plant Solanum tuberosum and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Nativ… hub motor cooling
