- Name origin (IAU)
- From the pre-Islamic Arabian lunar mansion name al-zubra, "the Mane, or Shoulder," for δ and θ Leo, associated with the pre-Islamic Arabian asterism al-asad (see ε Gem; al-zubra was an alternative name for al-kharatan given under θ Leo). "Subra" was wrongly applied as a star name too Leo in recent times.

In everyday life
- Light from this object takes about 130 years to reach Earth — the light you see tonight left around AD 1896 (official distance ÷ speed of light).
- At magnitude 3.5 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination 9.9° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
