Overview

ℹ️

FSR 0777 is a poorly populated, very dense object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, very young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.13 kpc) differs significantly from the median photometric distance (~1.08 kpc).

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