IC 2165 is a planetary nebula in Canis Major, 4,070 light-years away
IC 2165 (PK 221-12 1) is a planetary nebula in the constellation Canis Major , 4,070 light-years away. It shines at magnitude 10.5 and spans 9″ 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 February.
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.
