- n. astronomy an astronomical object with enough mass to achieve hydrostatic equilibrium, but not enough initiate core fusion at any time in its existence.

“Vision, there is a definition of a planetary mass object, called appropriately "planemo".”
“The only objects remaining with more than [[planemo | planetary mass]] will be [[brown dwarf]] s, with mass less than 0.08 solar masses, and [[compact star | degenerate remnants]]: [[white dwarf]] s, produced by stars with initial masses between about 0.08 and 8 solar masses, and”
