- Name origin (IAU)
- piautos (πιαυτος) is a composition from Greek autos ("self") and Coptic pi- ("that") meaning "the same one". It occurred in a Coptic manuscript on lunar stations. Coptic is the ancient Egyptian language written in Greek letters, but lunar stations were uncommon for both the Greek and Egyptian culture. Hence, the origin of this term remains unknown.

In everyday life
- Light from this object takes about 457 years to reach Earth — the light you see tonight left around AD 1569 (official distance ÷ speed of light).
- At magnitude 5.9 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
- Declination 24° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
