- Name origin (IAU)
- Applied in recent times from its pre-Islamic Arabian name al-sabiq, of uncertain meaning or connection. The name might mean literally "the Preceding One" or "the One Arriving First in a Race". Other sources give the name in the dualis form (for the two stars ζ and η Oph), and in the plural form (for more than two stars).

In everyday life
- Light from this object takes about 88 years to reach Earth — the light you see tonight left around AD 1938 (official distance ÷ speed of light).
- At magnitude 2.4 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination -15.7° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
