Overview

ℹ️

Theia 46 is a sparse, moderately dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

Note: This is very likely a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
