Pluto’s new friend – 2014 UZ224
A new dwarf planet has been discovered, looping around the sun, in the region beyond Pluto. This tiny ‘trans-Neptunian object’ is a finding that has added a new face to the solar system’s family portrait. UZ224, estimated to have a diameter of around 530 km, takes 1,100 years to complete a single orbit of the Sun. This dwarf planet has joined the ranks of: Ceres, Eris, Haumea, Makemake and of course Pluto.
