The Oceanus Moving Group: A New 500 Myr Old Host for the Nearest Brown Dwarf

We report the discovery of the Oceanus moving group, a ≈500 Myr old group with 50 members and candidate members at distances 2–50 pc from the Sun, using an unsupervised clustering analysis of nearby stars with Gaia DR3 data. This new moving group includes the nearest brown dwarf WISE J104915.57–5319...
