The new objects, 2014 FZ71 and 2015 FJ345, are in resonance with Neptune’s orbit, implying that these worlds either have interacted with Neptune in the past or are continuing to do so.

An international team of astronomers recently announced the discovery of an astonishing number of faint low surface brightness dwarf galaxies in the Fornax Cluster, suggesting that the “missing satellites” are now being found.
