NGC 358 is a very small open cluster of four stars in the constellation of Cassiopeia. It was originally thought to be an unrelated asterism, but two of the members were found to have a similar distance of roughly 1700 light years, although the other two do not have well-constrained distances, so its exact nature is uncertain.
The asterism was discovered on February 4, 1865 by the German-Danish astronomer Heinrich Louis d'Arrest.[3]
