missing‘,

or doubty, Messier object. This means that two opinions on the identity of

this object are common:

  1. M102 may be a duplication of the

    Spiral Galaxy

    M101 (NGC 5457)

    in Ursa Major,

    due to an error of either the catalog author Messier,

    or its `discoverer’ Mechain.

  2. M102 may be the

    Lenticular Galaxy

    NGC 5866

    in Draco,

    also sometimes called the Spindle Galaxy,

    as Messier’s catalog description indicates, together with the position

    he added later by hand.

The authors of this page think that there is enough evidence that both

Mechain and Messier have probably observed NGC 5866 in context of this

catalog entry. Therefore, it should be considered to take this last

missing object back into the catalog.

more details on this topic.
