IC 4191 is a planetary nebula in Musca, 8,820 light-years away
IC 4191 (ESO 096-002) is a planetary nebula in the constellation Musca , 8,820 light-years away. It shines at magnitude 10.6 and spans 5″ of sky, about 0.2 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in May.
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.
