Overview
ℹ️
NGC 7086 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Almeida et al. (2025)
Mass determination: good fit. Isochrone match: good fit. Silver sample.

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD class: 0.94 (50th percentile).

Richer et al. (2021)
The expected number of WDs is 46.0, 0 WD candidates found, and 0 WD candidates found in the wide search.

Piecka & Paunzen (2021)
Belongs to cluster aggregate 'Agg28' along with FSR 0306.
