In everyday life
- Light from this object takes about 399 years to reach Earth — the light you see tonight left around AD 1627 (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 33.1° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
