Object data of M45 |
||
| Object type: | Open star cluster (I3r) with reflection nebula | |
| Size: | 110' | |
| Magnitude: | 1.6 mag | |
| Constellation: | Tau | |
| Distance: | 440 Ly | |
| Notes: | The Pleiades nebulae are blue-colored, which indicates that they are reflection nebulae, reflecting the light of the bright stars situated near (or within) them. Physically, the reflection nebula is probably part of the dust in a molecular cloud, unrelated to the Pleiades cluster, which happens to cross the cluster's way. It is not a remainder of the nebula from which the cluster once formed. | |
