IC 5117 is a planetary nebula in Cygnus
IC 5117 (PK 89-05 1) is a planetary nebula in the constellation Cygnus . It shines at magnitude 11.5 and spans 1″. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in September.
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.
