| Object type: | Emission Nebula | |
| Size: | 7 light years across | |
| Magnitude: | 10th | |
| Constellation: | Cassiopeia | |
| Distance: | 10,000 light years | |
| Notes: | Formed by stellar winds (4 million miles/hr) from a massive star sweeping the cold interstellar gas in front, forming the outer edge of a bubble. As the surface of the bubble's shell expands it slams into dense regions of cold gas on one side creating an asymmetry. | |
