Overview
ℹī¸
Platais 10 is a moderately populated, very dense object of intermediate 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, intermediate-age cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is very well-studied in the literature.
Very close Low extinction Low mass Near-solar metallicity Intermediate age
