Although it appears about 15′ wide on the sky, its real span is roughly 31 light-years — the difference is a measure of how far away it lies.
Observing Bubble Nebula
Bubble Nebula lies in the constellation Cassiopeia and is best placed in the evening sky around September. Its maximum altitude above the horizon depends on your latitude. It sits far enough north to be circumpolar from mid-northern latitudes, and never rises for most of the southern hemisphere. Note that the listed magnitude is spread across the whole object — diffuse galaxies and nebulae are often harder to see than the number alone suggests, so dark, moonless skies help a great deal.
