Overview

ℹ️

ASCC 24 is a sparse, dense object of high C3 quality. Its parallax locates it at a very close distance, near the mid-plane, affected by low extinction. It is catalogued as a low-mass, near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption parameter (see Parameters). It is moderately studied in the literature.

Very close Low extinction Low mass Near-solar metallicity Very young
