IC 4776 is a planetary nebula in Sagittarius, 16,200 light-years away
IC 4776 (ESO 396-002) is a planetary nebula in the constellation Sagittarius , 16,200 light-years away. It shines at magnitude 10.8 and spans 7″ of sky, about 0.6 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in August.
Planetary nebula: a shell of gas thrown off by a dying Sun-like star and lit by the hot core left behind, which becomes a white dwarf. The name comes from their small, round, planet-like look in early telescopes.
