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 ...
A dedicated column for each of these sources inidcates whether an object is considered to be a centaur ( ) or not ( ). [b] The table highlights red and grey centaurs with a distinct background color (see legend). [2] [c] Legend Grey centaur (52 objs.) Red centaur (32 objs.) Centaur w/o color indices (439 objs.)
This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...

7066 Nessus / ˈ n ɛ s ə s / is a very red centaur on an eccentric orbit, located beyond Saturn in the outer Solar System.It was discovered on 26 April 1993, by astronomers of the Spacewatch program at the Kitt Peak National Observatory in Tucson, Arizona. [1]
5145 Pholus / ˈ f oʊ l ə s / is an eccentric centaur in the outer Solar System, approximately 180 kilometers (110 miles) in diameter, that crosses the orbit of both Saturn and Neptune. It was discovered on 9 January 1992 by American astronomer David Rabinowitz (uncredited) of UA 's Spacewatch survey at the Kitt Peak National Observatory in ...
Absolute magnitude (with electromagnetic wave, 'light' band denoted in subscript) is a measurement at a 10-parsec distance across imaginary empty space devoid of all its sparse dust and gas. Some of the parallaxes and resultant distances are rough measurements.
Ten years later, young blue stars were found along the central dust band with the Hubble Space Telescope. [27] The Chandra X-ray Observatory identified in 1999 more than 200 new point sources. [28] Another space telescope, the Spitzer Space Telescope, found a parallelogram-shaped structure of dust in near infrared images of Centaurus A in 2006 ...
