Overview
ℹī¸
LDN 988e is a rich, very dense object of high C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by high extinction. It is catalogued as a low-mass, near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.
