Overview
ℹī¸
Gulliver 18 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

Note: This is very likely a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
