a mountain doing 50,000 mph that occasionally forgets where the empty parts of space are
means A rocky body smaller than a planet that orbits the sun, mostly found in the belt between Mars and Jupiter.
from From the Greek 'asteroeidēs,' meaning 'star-like' — from 'astēr' (star) plus '-eidēs' (form, shape). The name was coined in the early 1800s, when these new objects were too small to show a disc in a telescope and looked exactly like faint stars. The astronomer William Herschel is generally credited with pushing the term, and the 'astēr' root is the same one that lights up 'astronomy,' 'astral,' and 'disaster' (literally 'bad star').
