Saturn Nebula is a planetary nebula in Aquarius, 3,760 light-years away
Saturn Nebula (Caldwell 55, NGC 7009, Herschel 400 no. 377) is a planetary nebula in the constellation Aquarius , 3,760 light-years away. It shines at magnitude 8.0 and spans 42″ × 30″ of sky, about 0.8 light-years across. It is best in a small telescope, 4 to 6 inches, 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.
