Overview

ℹ️

Theia 1742 is a moderately populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, 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.
