In planetary astronomy, a centaur is a small Solar System body that orbits the Sun between Jupiter and Neptune and crosses the orbits of one or more of the giant planets. . Centaurs generally have unstable orbits because of this; almost all their orbits have dynamic lifetimes of only a few million years, [1] but there is one known centaur, 514107 Kaʻepaokaʻawela, which may be in a stable ...
The following is a list of centaurs, a group of non-resonant small Solar System bodies whose orbit around the Sun lie typically between the orbits of Jupiter and Neptune (5 to 30 AU).

Nessus is a centaur, a dynamically unstable population of minor planets between the classical asteroids and the trans-Neptunian objects.It orbits the Sun at a distance of 11.9–37.4 AU once every 122 years and 4 months (44,670 days; semi-major axis of 24.64 AU).
54598 Bienor / b aɪ ˈ iː n ɔːr / is a centaur that grazes the orbit of Uranus. It is named after the mythological centaur Bienor. Its closest approach to the Sun is 13.2 AU. [2] As of 2020, Bienor is 14.2 AU from the Sun [7] and will reach perihelion in January 2028. [2] It measured approximately 198 kilometers (120 miles) in diameter. [4]
The term "Kármán line" was invented by Andrew G. Haley in a 1959 paper, [20] based on the chart in von Kármán's 1956 paper, but Haley acknowledged that the 275,000 feet (52.08 mi; 83.82 km) limit was theoretical and would change as technology improved, as the minimum speed in von Kármán's calculations was based on the speed-to-weight ...
The primary and secondary are both blue-white hued stars of magnitude 2.9; their period is 84 years. [2] Centaurus also has many dimmer double stars and binary stars. 3 Centauri is a double star with a blue-white hued primary of magnitude 4.5 and a secondary of magnitude 6.0. The primary is 344 light-years away.
