Object data of NGC2818 |
||
| Object type: | Planetary nebula | |
| Size: | 2' | |
| Magnitude: | 11.9 mag | |
| Constellation: | Pyx | |
| Distance: | 10,400 Ly | |
| Notes: | NGC 2818 is a planetary nebula located in the southern constellation Pyxis. Curiously, NGC 2818 seems to lie within an open star cluster, NGC 2818A, that is some 10,000 light-years distant. But accurate velocity measurements show that the nebula's own velocity is very different from the cluster's member stars. The result is strong evidence that NGC 2818 is only by chance found along the line of sight to the star cluster and so may not share the cluster's distance or age. | |
