Cone Nebula is a H II region in Monoceros, 2,280 light-years away
Cone Nebula (NGC 2264, LBN 911) is a H II region in the constellation Monoceros , 2,280 light-years away. It shines at magnitude 3.9 and spans 3′ × 10′ of sky, about 2.0 light-years across. It is visible to the naked eye from a dark site, and it is highest in the evening sky in February.
Nebula: a cloud of gas and dust. Emission nebulae glow on their own, lit by ultraviolet light from hot young stars; reflection nebulae shine by starlight scattered from dust; dark nebulae block the light behind them.
