Dwarf planets are round for the same reason planets are, gravity, but share their orbit with other bodies a full planet would have swept aside or absorbed.
At 1,430 km across, Makemake is 11 percent of the diameter of Earth.
Its mass is less than a thousandth of the mass of Earth.
It keeps an average distance of 45.79 AU from the Sun, so sunlight takes 6.3 hours to reach it.
A single orbit takes 306 years.
An average temperature of 30 K works out at -243 degrees Celsius, colder than the 15 degrees Earth averages.
One moon is known to orbit it.
It has been on record since 2005.
