In everyday life
- Light from this object takes about 170 years to reach Earth — the light you see tonight left around AD 1856 (official distance ÷ speed of light).
- At magnitude 9.3 it is fainter than the naked-eye limit (about 6) — you need binoculars or a telescope.
- Declination -36.6° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
