- From its ancient Greek name ἀντάρης, "like Ares", likening the red colour of this star to its planetary namesake (the Roman Mars), name occurs in the Almagest. Possibly the Greek name goes back to a Sumerian precursor AN.TA.GUB (as suggested by Horowitz).

In everyday life
- Light from this object takes about 554 years to reach Earth — the light you see tonight left around AD 1472 (official distance ÷ speed of light).
- At magnitude 0.9 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination -26.4° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
