Can you name all five dwarf planets? This week the International Astronomical Union announced the naming of the fifth one. Haumea (pronounced how-MAY-uh).
Although its discovery has been disputed, three of the five named dwarf planets (as sizable majority) have been found here at Palomar using the 48-inch Samuel Oschin Telescope. The graphic above shows the largest worlds that are known to lie beyond Neptune. Six of the eight worlds have been found using the Samuel Oschin Telescope.
The five named dwarf planets are: Ceres, Pluto, Eris, Makemake & Haumea.
