New Dwarf?
This animation shows the body designated 2017 OF201 moving against the background of stars. Discovered in 2017, it could be the newest member of the dwarf-planet category, which includes Pluto. It may be about one-third the size of Pluto, and it takes almost 25,000 years to complete one orbit around the Sun. [Jean-Marc Petit/CFHT/Canadian Astronomy Data Centre]
