Cataloged by Hodierna before 1654.
This moving cluster was probably first cataloged as a nebulous object by Hodierna. It was described as stellar group by Eddington 1910, and cataloged by Melotte 1915.
The distance of this cluster has recently been measured by ESA's Hipparcos satellite, as 601 light years (previously, it had been thought to be at 554 light years).
