Name origin (IAU): A Latin name meaning "the Female Warrior", given to α Aur in a medieval astrological text (the reason behind this initial application is not fully understood and awaits further findings in corresponding Arabic texts). In late medieval times, bellatrix was transferred to γ Ori, perhaps by association with the name Bellator, "the Male Warrior", which was used for Orion in other astrological texts.

Constellation

Light from this object takes about 252 years to reach Earth — the light you see tonight left around AD 1774 (official distance ÷ speed of light).
At magnitude 1.6 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination 6.3° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
