A minor-planet moon is an astronomical object that a minor planet as its natural satellite. , there are 457 minor planets known or suspected to have moons.
Several of the moons are quite large compared to their primaries: 90 Antiope, Mors–Somnus and Sila–Nunam (95%), Patroclus–Menoetius, Altjira and Lempo–Hiisi (90%, with Lempo–Paha at 50%). The largest known minor-planet moon in absolute size is Pluto's largest moon Charon, which itself has about half the diameter of Pluto.
There are also several known ring systems around distant objects (see: Rings of Chariklo and Chiron).
Terminology
In addition to the terms
satellite and
moon, the term "binary" (
binary minor planet) is sometimes used for minor planets with one moon, and "triple" for minor planets with two moons. If one object is much bigger it is referred to as the
primary and its companion as the
secondary. The term
double asteroid is sometimes used for systems in which the asteroid and its moon are roughly the same size, while
binary tends to be used independently from the relative sizes of the components. When binary minor planets are similar in size, the Minor Planet Center (MPC) refers to them as "
Binary asteroid" instead of referring to the smaller body as a satellite.
A good example of a true binary is the 90 Antiope system, identified in August 2000.
Very small satellites are often referred to as moonlets.
Discovery milestones
Prior to the era of the Hubble Space Telescope and space probes reaching the outer Solar System, attempts to detect satellites around asteroids were limited to optical observations from Earth. For example, in 1978, stellar occultation observations were claimed as evidence of a satellite for the asteroid to 532 Herculina.
However, later more-detailed imaging by the Hubble Telescope did not reveal a satellite, and the current consensus is that Herculina does not have a significant satellite.
There were other similar reports of asteroids having companions (usually referred to as satellites) in the following years. A letter by astronomer Thomas Hamilton in the
Sky & Telescope magazine at this time pointed to apparently simultaneous impact craters on Earth (for example, the
Clearwater Lakes in Quebec), suggesting that these craters were caused by pairs of gravitationally bound objects.
In 2014, 130 Elektra was discovered to have three moons, making it the only discovered quadruple asteroid.
Also in 1978, Pluto's largest moon Charon was discovered; however, at the time Pluto was still considered to be one of the major planets.
In 1993, the first asteroid moon was confirmed when the Galileo probe probe discovered the small Dactyl orbiting 243 Ida in the asteroid belt. The second was discovered around 45 Eugenia in 1998.
Multiple systems
In 2005, the asteroid 87 Sylvia was discovered to have two satellites, making it the first known triple system (also called a
triple minor planet or
triple asteroid).
This was followed by the discovery of a second moon orbiting 45 Eugenia.
Also in 2005, the dwarf planet was discovered to have two moons, making it the second trans-Neptunian object after
Pluto known to have more than one moon.
Additionally, 216 Kleopatra
and 93 Minerva
were discovered to be triple asteroids in 2008 and 2009 respectively. There has been one discovered quadruple minor planet, that being 130 Elektra. Since the first few triple minor planets were discovered, more continue to be discovered. , the total number of known multiple systems among minor planets is 18 (including the Pluto and Haumea systems).
The following table lists all satellites of multiple systems, starting with Pluto, which was unnumbered when its first moon was discovered in 1978. The highest known multiplicities are for Pluto (a sextuple system) and 130 Elektra (a quadruple system).

Commonality
The data about the populations of binary objects are still patchy. In addition to the inevitable observational bias (dependence on the distance from Earth, size,
albedo and separation of the components) the frequency appears to be different among different categories of objects. Among asteroids, an estimated 2% would have satellites. Among trans-Neptunian objects (TNOs), an estimated 11% are thought to be binary or multiple objects, and the majority of the large TNOs have at least one satellite, including all four IAU-listed dwarf planets.
More than 50 binaries are known in each of the main groupings: near-Earth asteroids, asteroid belt, and trans-Neptunian objects, not including numerous claims based solely on light-curve variation.
Two binaries have been found so far among centaurs with semi-major axis smaller than Neptune.
Origin
The origin of minor-planet moons is not currently known with certainty, and a variety of hypotheses exist. One such model is that minor-planet moons are formed from debris knocked off the primary by an impact. Other pairings may be formed when a small object is captured by the gravity of a larger one.
Formation by collision is constrained by the angular momentum of the components, i.e. by the masses and their separation. Close binaries fit this model (e.g. Pluto–Charon). Distant binaries however, with components of comparable size, are unlikely to have followed this scenario, unless considerable mass has been lost in the event.
The distances of the components for the known binaries vary from a few hundreds of kilometres (243 Ida, 3749 Balam) to more than 3000 km (379 Huenna) for the asteroids. Among TNOs, the known separations vary from 3,000 to 50,000 km.
Populations and classes
What is "typical" for a binary system tends to depend on its location in the Solar System (presumably because of different modes of origin and lifetimes of such systems in different populations of minor planets).
-
Among near-Earth asteroids, satellites tend to orbit at distances of the order of 3–7 primary radii, and have diameters two to several times smaller than the primary. Since these binaries are all inner-planet crossers, it is thought that tidal stresses that occurred when the parent object passed close to a planet may be responsible for the formation of many of them, although collisions are thought to also be a factor in the creation of these satellites.
-
Among main-belt , the satellites are usually much smaller than the primary (a notable exception being 90 Antiope), and orbit around 10 primary radii away. Many of the binary systems here are members of asteroid family, and a good proportion of satellites are expected to be fragments of a parent body whose disruption after an asteroid collision produced both the primary and satellite.
-
Among trans-Neptunian objects, it is common for the two orbiting components to be of comparable size, and for the semi-major axis of their orbits to be much larger − about 100 to 1000 primary radii. A significant proportion of these binaries are expected to be primordial.
-
Pluto has five known moons. Its largest moon Charon has a radius of more than half that of Pluto, and is large enough to orbit a point outside Pluto's surface. In fact, each orbits the common barycenter between them, with Pluto's orbit entirely enclosed by Charon's; thus they form a binary system informally referred to as a double planet. Pluto's four other moons, Nix, Hydra, Kerberos, and Styx, are far smaller and orbit the Pluto–Charon system.
-
Haumea has two moons with radii estimated around 155 km (Hiʻiaka) and 85 km (Namaka).
-
has one known moon, S/2015 (136472) 1, estimated to be some in diameter.
-
47171 Lempo is a unique trans-Neptunian triple system: Lempo and its moon of roughly equal mass, Hiisi, form a close-proximity binary, separated by roughly 867 km. A second moon, Paha, orbits the Lempo–Hiisi binary at about 7411 km.
-
has one known moon, Dysnomia. Its radius, based on its brightness, is estimated to be roughly between 150 and 350 km.
