Trans-Neptunian objects

V774104 is a trans-Neptunian object (TNO) with a radius roughly half that of Pluto or somewhat smaller.

Dysnomia (Greek: Δυσνομία)—officially (136199) Eris I Dysnomia—is the only known moon of the dwarf planet Eris (the most massive known dwarf planet in the Solar System).

This is a list of trans-Neptunian objects (TNO) in the Solar System, along with a list of their moons.

90377 Sedna is a large minor planet in the outer reaches of the Solar System that was, as of 2015, at a distance of about 86 astronomical units (AU) from the Sun, about three times as far as Neptune.

Following the discovery of the planet Neptune in 1846, there was considerable speculation that another planet might exist beyond its orbit.

Hiʻiaka is the larger, outer moon of the dwarf planet Haumea.

Planet Nine is a hypothetical large planet in the far outer Solar System, the gravitational effects of which would explain the improbable orbital configuration of a group of trans-Neptunian objects (TNOs) that orbit mostly beyond the Kuiper belt.

42355 Typhon (/ˈtaɪfɒn/; from Greek: Τυφών) is a scattered disc object that was discovered on February 5, 2002, by the NEAT program.

Namaka is the smaller, inner moon of the dwarf planet Haumea.

Detached objects are a dynamical class of minor planets in the outer reaches of the Solar System and belong to the broader family of trans-Neptunian objects (TNOs).

Weywot, officially (50000) Quaoar I Weywot, is the only known moon of the trans-Neptunian object Quaoar.

Actaea, officially (120347) Salacia I Actaea, is the single known natural satellite of the classical Kuiper belt object 120347 Salacia.

Vanth, officially (90482) Orcus I Vanth, is the single known natural satellite of the plutino and likely dwarf planet Orcus.

50000 Quaoar ("Kwawar") is a Kuiper belt object roughly half the size of Pluto, with a diameter of 1110±5 km.
