minigravity (n., slang): The level of gravity present on dwarf planets, small moons, large asteroids, et. al. While not rigorously defined, the minigravity range is commonly held to be between 0.2 and 0.005 standard gravities, anything below which is considered to be de facto microgravity. Unofficially, the range at which gravity is high enough to require your attention, but too low to rely upon.
