Makemake (minor-planet designation 136472 Makemake) is a dwarf planet and perhaps the largest Kuiper belt object in the classical population, with a diameter approximately two thirds that of Pluto. Makemake has one known satellite, S/2015 (136472) 1. Makemake’s extremely low average temperature, about 30 K (−243.2 °C), means its surface is covered with methane, ethane, and possibly nitrogen ices.
Makemake was discovered on March 31, 2005, by a team led by Michael E. Brown, and announced on July 29, 2005. Initially, it was known as 2005 FY9 and later given the minor-planet number 136472. Makemake was recognized as a dwarf planet by the International Astronomical Union (IAU) in July 2008. Its name derives from Makemake in the mythology of the Rapa Nui people of Easter Island. — Wikipedia

Pluto's status as a "dwarf planet" is once again stirring debate. This comes as some planetary scientists are trying to have Pluto reclassified as a planet – a wish that's not likely to come true. […]
A geophysical planet definition

In 2006, during their 26th General Assembly, the International Astronomical Union (IAU) adopted a formal definition of the term "planet". This was done in the hopes of dispelling ambiguity over which bodies should be designated as "planets", an issue that had plagued astronomers ever since they discovered objects beyond the orbit of Neptune that were comparable in size to Pluto. […]
New dwarf planet found in our solar system

(Phys.org)—A team of space scientists at the University of Michigan has discovered a dwarf planet that is approximately half the size of Pluto and twice as far from the sun. The sighting was reported by NPR, which interviewed team lead physicist David Gerdes. He told them credit goes to a group of students who were challenged to find some new objects to add to the ongoing construction of a galaxy map. Their efforts led to software that can be used to analyze imagery from the Dark Energy […]

A Southwest Research Institute-led team has discovered an elusive, dark moon orbiting Makemake, one of the "big four" dwarf planets populating the Kuiper Belt region at the edge of our solar system. The findings are detailed in the paper "Discovery of a Makemakean Moon," published in the June 27 issue of Astrophysical Journal Letters. […]

Haumea, a dwarf planet on the edge of our solar system doesn't have the same kind of moons as its well-known cousin Pluto according to a new study. This is despite original evidence that suggested they both formed in similar giant impacts and adds to the mystery shrouding how these icy bodies formed.&nbs […]
