**NGC 5866** (also called the **Spindle Galaxy** or possibly '[Messier 102](/source/Messier_102)') is a [lenticular](/source/Lenticular_galaxy) galaxy in the [constellation](/source/Constellation) [Draco](/source/Draco_(constellation)). NGC 5866 was most likely discovered by [Pierre Méchain](/source/Pierre_M%C3%A9chain) or [Charles Messier](/source/Charles_Messier) in 1781, and independently found by [William Herschel](/source/William_Herschel) in 1788. Measured orbital velocities of its [globular cluster](/source/Globular_cluster) system[6] imply that [dark matter](/source/Dark_matter) makes up only 34%±45% of the mass within 5 [effective radii](/source/Galaxy_effective_radius), a notable paucity.

## Dust lane

One of the most outstanding features of NGC 5866 is the extended dust disk, which is seen almost exactly edge-on.[7] This [dust lane](/source/Dust_lane) is highly unusual for a [lenticular galaxy](/source/Lenticular_galaxy). The dust in most lenticular galaxies is generally found only near the nucleus and generally follows the light profile of the galaxies' bulges.[8][9] This dust disk may contain a ring-like structure, although the shape of this structure is difficult to determine given the edge-on orientation of the galaxy.[9] It is also possible that the galaxy is a [spiral galaxy](/source/Spiral_galaxy) that was misclassified as a lenticular galaxy because of its edge-on orientation, in which case the dust lane would not be too unusual.[8]

## Galaxy group information

NGC 5866 is one of the brightest galaxies in the [NGC 5866 Group](/source/NGC_5866_Group), a small [galaxy group](/source/Galaxy_group) that also includes the [spiral galaxies](/source/Spiral_galaxies) [NGC 5879](/source/NGC_5879) and [NGC 5907](/source/NGC_5907).[10][11][12] This group may actually be a subclump at the northwest end of a large, elongated structure that comprises the [M51 Group](/source/M51_Group) and the [M101 Group](/source/M101_Group), although most sources distinguish the three groups as separate entities.[13]
