- A Latin word meaning "hip", used in the Medieval Latin Almagest in describing σ and ι/38 Aqr in the right and left hips, respectively (following an error, for Ptolemy had these stars in "the buttocks"). The word was applied as a star name to θ Aqr (correctly in Ptolemy's "right socket of the hip") in recent times.

In everyday life
- Light from this object takes about 187 years to reach Earth — the light you see tonight left around AD 1839 (official distance ÷ speed of light).
- At magnitude 4.2 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination -7.8° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
