In everyday life
- Light from this object takes about 832 years to reach Earth — the light you see tonight left around AD 1194 (official distance ÷ speed of light).
- At magnitude 12.3 it is fainter than the naked-eye limit (about 6) — you need binoculars or a telescope.
- Declination 32.2° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
