Constellation

Light from this object takes about 253 years to reach Earth — the light you see tonight left around AD 1773 (official distance ÷ speed of light).
At magnitude 4.8 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination -12.8° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
