Makemake is a classical Kuiper belt object (KBO), [5] [b] which means its orbit lies far enough from Neptune to remain stable over the age of the Solar System. [ 45 ] [ 46 ] Unlike plutinos , which can cross Neptune's orbit due to their 2:3 resonance with the planet, the classical objects have perihelia further from the Sun, free from Neptune's ...
Makemake is the third-largest known dwarf planet in the Solar System and one of the two largest Kuiper belt objects (KBO) in the classical KBO population. Its diameter is roughly three-quarters that of Pluto. Makemake has no known satellites, which makes it unique among the largest KBOs.
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
S/2015 (136472) 1, unofficially nicknamed MK2 by the discovery team, [2] is the only known moon of the trans-Neptunian dwarf planet Makemake. [1] [4] It is estimated to be 175 km (110 mi) in diameter and has a semi-major axis of at least 21,000 km (13,000 mi) from Makemake. [1] Its orbital period is at least 12 days if it has a circular orbit.
Largest moons to scale with their parent planets and dwarf planet. Besides planets and dwarf planets objects within our Solar System known to have natural satellites are 76 in the asteroid belt (five with two each), four Jupiter trojans, 39 near-Earth objects (two with two satellites each), and 14 Mars-crossers.

A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which for decades was regarded as a planet before the "dwarf" concept ...
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
