A trans-Neptunian object (TNO), also written transneptunian object, [1] is any minor planet in the Solar System that orbits the Sun at a greater average distance than Neptune, which has an orbital semi-major axis of 30.1 astronomical units (AU).
This is a list of trans-Neptunian objects (TNOs), which are minor planets in the Solar System that orbit the Sun at a greater distance on average than Neptune, that is, their orbit has a semi-major axis greater than 30.1 astronomical units (AU). The Kuiper belt, scattered disk, and Oort cloud are three conventional divisions of this volume of ...
The term "trans-Neptunian object" (TNO) is recommended for objects in the belt by several scientific groups because the term is less controversial than all others—it is not an exact synonym though, as TNOs include all objects orbiting the Sun past the orbit of Neptune, not just those in the Kuiper belt.
The orbits of Sedna, 2012 VP 113, Leleākūhonua, and other very distant objects along with the predicted orbit of Planet Nine [A] An extreme trans-Neptunian object (ETNO) is a trans-Neptunian object orbiting the Sun well beyond Neptune (30 AU) in the outermost region of the Solar System. An ETNO has a large semi-major axis of at least 150 ...
In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.
Objects in the Solar System whose orbit lies beyond that of Neptune. ... List of unnumbered trans-Neptunian objects; 0–9. 1996 PW (612051) 1997 SZ10; 1999 OZ3; 2002 ...
471325 Taowu (provisional designation 2011 KT 19, formerly nicknamed Niku (/ n iː k uː /)) is a trans-Neptunian object whose orbit is tilted 110° with respect to the planets' orbital plane. Thus, it has a nearly polar retrograde orbit around the Sun .
Objects beyond a distance of 100 AU display their designation. Resonant TNO & Plutino Cubewanos (classical KBO) Scattered disc object Detached object. 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).
