omicron

name

1. Ellipsis of Omicron Hill: a mountain in North Slope borough, Alaska, United States.

noun

Etymology: From Latin omicron, from Koine Greek ὂ μῑκρόν (ò mīkrón, “little o”), named in contrast with omega (“big o”). The uncommon form omicra is similarly borrowed from Latin and Greek. The use for designating stars in a constellation—typically in order of apparent brightness—began with Johann Bayer's 1603 Uranometria.
