Overview

ℹ️

Sh2-235 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by high extinction. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature.

Note: This object shares a small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Relatively close High extinction Very young

Bica et al. (2003)
Classified as infrared cluster (IRC).
