Overview

ℹ️

SAI 143 is a sparse, loose object of low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by very high extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.37 kpc) differs significantly from the median photometric distance (~9.00 kpc).

Very distant Very high extinction Massive Intermediate age
