This is a list of Solar System objects by size, arranged in descending order of mean volumetric radius

In classical geometry, a radius of a circle or sphere is any line segment from its center to its perimeter. By extension, the radius of a circle or sphere is the length of any such segment, which is half the diameter....

Several new trans-Neptunian objects (TNOs) have been discovered of significant size. While their radius remains provisional due to the recency of discovery, and is often expressed as a range, the approximate locations in this list are shown.

 from their rotation, but a characteristic feature of the "irregular"-shaped bodies is that there is a significant difference in the length of their two equatorial diameters.

There appears to be difficulty in figuring out the diameter (within a factor of about 2) for typical objects beyond Saturn. (See 2060 Chiron as an example.) For TNOs there is some confidence in the diameters, but for non-binary TNOs there is no real confidence in the "unreferenced wiki-assumed" masses/densities. Many TNOs are just assumed to have a density of 2.0 g/cm³, though it is just as likely that they have a comet like density of only 0.5 g/cm³. Thus most provisional TNOs are not given a MEarth value to prevent from cluttering the list with too many assumptions that could be off by an order of magnitude

An order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it. In its most common usage, the amount being scaled is 10 and the scale is the exponent being applied to this amount...

The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters. But many of the moons with a radius less than ~100 km, such as Jupiter's Himalia

 from their rotation, but a characteristic feature of the "irregular"-shaped bodies is that there is a significant difference in the length of their two equatorial diameters.

There appears to be difficulty in figuring out the diameter (within a factor of about 2) for typical objects beyond Saturn. (See 2060 Chiron as an example.) For TNOs there is some confidence in the diameters, but for non-binary TNOs there is no real confidence in the "unreferenced wiki-assumed" masses/densities. Many TNOs are just assumed to have a density of 2.0 g/cm³, though it is just as likely that they have a comet like density of only 0.5 g/cm³. Thus most provisional TNOs are not given a MEarth value to prevent from cluttering the list with too many assumptions that could be off by an order of magnitude

 from their rotation, but a characteristic feature of the "irregular"-shaped bodies is that there is a significant difference in the length of their two equatorial diameters.

There appears to be difficulty in figuring out the diameter (within a factor of about 2) for typical objects beyond Saturn. (See 2060 Chiron as an example.) For TNOs there is some confidence in the diameters, but for non-binary TNOs there is no real confidence in the "unreferenced wiki-assumed" masses/densities. Many TNOs are just assumed to have a density of 2.0 g/cm³, though it is just as likely that they have a comet like density of only 0.5 g/cm³. Thus most provisional TNOs are not given a MEarth value to prevent from cluttering the list with too many assumptions that could be off by an order of magnitude
Order of magnitude
An order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it. In its most common usage, the amount being scaled is 10 and the scale is the exponent being applied to this amount...

The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters. But many of the moons with a radius less than ~100 km, such as Jupiter's Himalia

Objects between 200 and 100 km in radius


The largest of these objects just might lie above the boundary for hydrostatic equilibrium, but most are irregular. Most of the Trans-Neptunian object
Trans-Neptunian object
A trans-Neptunian object is any object in the Solar System that orbits the Sun at a greater distance on average than Neptune. The Kuiper belt, scattered disk, and Oort cloud are three divisions of this volume of space....

s listed with a radius smaller than 200 km have "assumed sizes based on a generic albedo of 0.09" since they are too far away to directly measure their sizes. Volume and surface gravity are difficult to calculate for irregular objects. Values relative to Earth are too inexact to be useful beyond this point. Mass switches from 1021 kg to 1018 kg (Zg), with Mimas double listed as example of unit shift. Main belt asteroids have orbital elements constrained by (2.0 AU < a < 3.2 AU; q > 1.666 AU) according to JPL Solar System Dynamics (JPLSSD).
