List of Solar System objects by size

Short description: none

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 massive objects, volume, density, and surface gravity, if these values are available.

These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.

Many trans-Neptunian objects (TNOs) have been discovered; in many cases their positions in this list are approximate, as there is frequently a large uncertainty in their estimated diameters due to their distance from Earth. There are uncertainties in the figures for mass and radius, and irregularities in the shape and density, with accuracy often depending on how close the object is to Earth or whether it has been visited by a probe.

Solar System objects more massive than 10²¹ kilograms are known or expected to be approximately spherical. Astronomical bodies relax into rounded shapes (spheroids), achieving hydrostatic equilibrium, when their own gravity is sufficient to overcome the structural strength of their material. It was believed that the cutoff for round objects is somewhere between 100 km and 200 km in radius if they have a large amount of ice in their makeup;^[1] however, later studies revealed that icy satellites as large as Iapetus (1,470 kilometers in diameter) are not in hydrostatic equilibrium at this time,^[2] and a 2019 assessment suggests that many TNOs in the size range of 400–1,000 kilometers may not even be fully solid bodies, much less gravitationally rounded.^[3] Objects that are ellipsoids due to their own gravity are here generally referred to as being "round", whether or not they are actually in equilibrium today, while objects that are clearly not ellipsoidal are referred to as being "irregular".

Spheroidal bodies typically have some polar flattening due to the centrifugal force from their rotation, and can sometimes even have quite different equatorial diameters (scalene ellipsoids such as Haumea). Unlike bodies such as Haumea, the irregular bodies have a significantly non-ellipsoidal profile, often with sharp edges.

There can be difficulty in determining the diameter (within a factor of about 2) for typical objects beyond Saturn (see: 2060 Chiron § Physical characteristics, for an example). For TNOs there is some confidence in the diameters, but for non-binary TNOs there is no real confidence in the masses/densities. Many TNOs are often just assumed to have Pluto's density of 2.0 g/cm³, but it is just as likely that they have a comet-like density of only 0.5 g/cm³.^[4]

For example, if a TNO is incorrectly assumed to have a mass of 3.59×10²⁰ kg based on a radius of 350 km with a density of 2 g/cm³ but is later discovered to have a radius of only 175 km with a density of 0.5 g/cm³, its true mass would be only 1.12×10¹⁹ kg.

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; however, many of the moons with a radius less than ≈100 km, such as Jupiter's Himalia, have far more uncertain masses.^[5] Further out from Saturn, the sizes and masses of objects are less clear. There has not yet been an orbiter around Uranus or Neptune for long-term study of their moons. For the small outer irregular moons of Uranus, such as Sycorax, which were not discovered by the Voyager 2 flyby, even different NASA web pages, such as the National Space Science Data Center^[6] and JPL Solar System Dynamics,^[5] give somewhat contradictory size and albedo estimates depending on which research paper is being cited.

Graphical overview

Relative diameters of the fifty largest measured bodies in the Solar System, colored by orbital region. Values are diameters in kilometers. Both scales are linear.

Relative masses of the bodies of the Solar System. Objects smaller than Saturn are not visible at this scale.
Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system.
Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale.

Objects with radii over 400 km

The following objects have a nominal volumetric radius of 400 km or greater. It was once expected that any icy body larger than approximately 200 km in radius was likely to be in hydrostatic equilibrium (HE).^[8] However, Ceres (r = 470 km) is the smallest body for which detailed measurements are consistent with hydrostatic equilibrium,^[9] whereas Iapetus (r = 735 km) is the largest icy body that has been found to not be in hydrostatic equilibrium.^[10] The known icy moons in this range are all ellipsoidal (except Proteus), but trans-Neptunian objects up to 300–350 km radius may be quite porous.^[11]

For simplicity and comparative purposes, the values are manually calculated assuming that the bodies are all spheres. The size of solid bodies does not include an object's atmosphere. For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure.^[12]

Because Sedna has no known moons, directly determining its mass is impossible without sending a probe.

Smaller objects by mean radius

From 200 to 399 km

All imaged icy moons with radii greater than 200 km except Proteus are clearly round, although those under 400 km that have had their shapes carefully measured are not in hydrostatic equilibrium.^[76] The known densities of TNOs in this size range are remarkably low (1–1.2 g/cm³), implying that the objects retain significant internal porosity from their formation and were never gravitationally compressed into fully solid bodies.^[11] Many intrinsically bright TNOs like 2018 VG18 and 2017 OF201 do not have directly measured sizes (e.g. via stellar occultation and radiometry of thermal emission), so their sizes are estimated based on an assumed albedo.^[77] In the list below, TNOs with unmeasured sizes are only listed if they have been mentioned in press releases and the scientific literature.

From 100 to 199 km

This list contains a selection of objects estimated to be between 100 and 199 km in radius (200 and 399 km in diameter), being 200 km nicknamed the "potato radius" by astronomers. The largest of these may have a hydrostatic-equilibrium shape, but most are irregular (i.e., potato-shaped). Mass switches from 10²¹ kg to 10¹⁸ kg (Zg). 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).^[130] Many TNOs are omitted from this list as their sizes are poorly known.^[77]

Below 1 km

This list contains examples of objects below 1 km in radius. That means that irregular bodies can have a longer chord in some directions, hence the mean radius averages out. In the asteroid belt alone there are estimated to be between 1.1 and 1.9 million objects with a radius above 0.5 km,^[300] many of which are in the range 0.5–1.0 km. Countless more have a radius below 0.5 km. Very few objects in this size range have been explored or even imaged. The exceptions are objects that have been visited by a probe, or have passed close enough to Earth to be imaged. Radius is by mean geometric radius. Number of digits not an endorsement of significant figures. Mass scale shifts from × 10¹⁵ to 10⁹ kg, which is equivalent to one billion kg or 10¹² grams (Teragram – Tg). Currently most of the objects of mass between 10⁹ kg to 10¹² kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR₁₂ has less mass than the Great Pyramid of Giza, 5.9 × 10⁹ kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and interplanetary dust cloud. (See also Visited/imaged bodies.)

This calculation does not treat Achlys as an ellipsoid (which would have a volume of $V = \frac{4}{3} π a b c \approx 1.85 \times 1 0^{17} m^{3}$ ), though the mass calculated from Achlys's ellipsoid volume and density ( $M = ρ V \approx 1.61 \times 1 0^{20} kg$ ) is equivalent to Muñoz-Gutiérrez et al.'s mass calculation when rounded to a single digit.

↑ Using Grundy et al.'s working diameters of 361 km and 163 km, and assuming the densities of the two bodies are equal, Varda would contribute 91.6% of the system mass of (2.664±0.064)×10²⁰ kg, meaning Varda's mass is about (2.44±0.06)×10²⁰ kg.^[85]
↑ very approximate figure, assuming equivalent spherical diameter of ≈600 km and density ≈2.64 g/cm³
↑ A density of 0.4–0.8 g/cm³ was calculated when assuming the volume as a sphere with a radius of 210±7 km.^[125] The mass was calculated with the provided density and the assumed volume.
↑ The mass estimate is based on the assumed density of 1.2 g/cm³, and a volume of 3.5 ×10⁶ km³ obtained from a detailed shape model in Stooke (1994).^[160]
↑ Fuentes-Muñoz et al. (2025) give Nysa's mass in terms of the standard gravitational parameter GM = 0.038444658±0.009560725 km³ s⁻² (or after converting to SI units, (3.8444658±0.9560725)×10⁷ m³ s⁻²).^[226] This can be converted into mass (M) by dividing GM (in SI units) by the gravitational constant G = 6.6743×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²^[227]. The resulting mass of Nysa is approximately M = (5.76±1.43)×10¹⁷ kg.

[equatorial-31] 1.0 ^1.1 ^1.2 ^1.3 ^1.4 Radius estimated using equatorial radius and assuming body is spherical

[various-47] 2.0 ^2.1 Radius has been determined by various methods, such as optical (Hubble), thermal (Spitzer), or direct imaging via spacecraft

[51] The mass of Eris by itself is the difference between the mass of the system ((1.6466±0.0085)×10²² kg)^[44] and the mass of Dysnomia by itself ((8.2±5.7)×10¹⁹ kg).^[45]

[three_radii-53] 4.0 ^4.1 Radius estimated by using three radii and assuming body is spheroid

[WolframVolume-58] Calculated in Wolfram Alpha using semi axes of 1050 × 840 × 537^[50](Ellipsoid volume: 1.98395×10^9 km³)

[HE-60] Best fit physical model assuming hydrostatic equilibrium for Haumea.^[50]

[system_mass-67] 7.0 ^7.1 ^7.2 ^7.3 This value refers to the system mass

[mc-93] Mass calculated by Muñoz-Gutiérrez et al. (2019 & 2021) using Achlys's area-equivalent diameter of 772 km and predicted density of 0.87 g/cm³.^[79]^: 2^[80]^: 2 Muñoz-Gutiérrez et al. give the mass in terms of Earth masses (M_🜨), which can be converted into kilograms by multiplying by 5.9722×10²⁴ kg/M_🜨. This calculation does not treat Achlys as an ellipsoid (which would have a volume of $V = \frac{4}{3} π a b c \approx 1.85 \times 1 0^{17} m^{3}$ ), though the mass calculated from Achlys's ellipsoid volume and density ( $M = ρ V \approx 1.61 \times 1 0^{20} kg$ ) is equivalent to Muñoz-Gutiérrez et al.'s mass calculation when rounded to a single digit.

[assumedalbedo-96] 9.00 ^9.01 ^9.02 ^9.03 ^9.04 ^9.05 ^9.06 ^9.07 ^9.08 ^9.09 ^9.10 Radius estimated from an assumed albedo

[wd-100] Using Grundy et al.'s working diameters of 361 km and 163 km, and assuming the densities of the two bodies are equal, Varda would contribute 91.6% of the system mass of (2.664±0.064)×10²⁰ kg, meaning Varda's mass is about (2.44±0.06)×10²⁰ kg.^[85]

[111] very approximate figure, assuming equivalent spherical diameter of ≈600 km and density ≈2.64 g/cm³

[142] A density of 0.4–0.8 g/cm³ was calculated when assuming the volume as a sphere with a radius of 210±7 km.^[125] The mass was calculated with the provided density and the assumed volume.

[mass_estimate-178] The mass estimate is based on the assumed density of 1.2 g/cm³, and a volume of 3.5 ×10⁶ km³ obtained from a detailed shape model in Stooke (1994).^[160]

[mass-246] Fuentes-Muñoz et al. (2025) give Nysa's mass in terms of the standard gravitational parameter GM = 0.038444658±0.009560725 km³ s⁻² (or after converting to SI units, (3.8444658±0.9560725)×10⁷ m³ s⁻²).^[226] This can be converted into mass (M) by dividing GM (in SI units) by the gravitational constant G = 6.6743×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²^[227]. The resulting mass of Nysa is approximately M = (5.76±1.43)×10¹⁷ kg.
