    The distant dwarf planet Makemake was discovered in 2005 but little is known about it. Makemake seems like a typical dwarf planet -- like Pluto and Eris -- but without accurate measurements for such a distant object it was not known whether it had an atmosphere (like Pluto) or lacks one (like Eris). New observations of Makemake seem to have resolved the question.
