Overview

ℹ️

Cep A is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a close distance, above the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 23 years.

⚠️ Warning: This is very likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
