Ursa

/ˈɜrsə/ noun

Definition

Latin word for 'bear,' used in astronomy to name two prominent constellations: Ursa Major (Great Bear) and Ursa Minor (Little Bear).

Etymology

From Latin 'ursa' directly meaning 'bear,' possibly descended from Proto-Indo-European '*h₂ŕ̥tko-.' Ancient astronomers named these constellations based on their resemblance to bears in the night sky.

Kelly Says

Ursa Major contains the Big Dipper asterism and has helped humans navigate for thousands of years—Polaris (the North Star) sits almost directly above it, making it the most useful constellation for finding true north.
