Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
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.)
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 ...
Size and shape [ edit ] Chariklo is currently the largest known centaur , with a volume-equivalent diameter of about 250 km. [ 10 ] Its shape is probably elongated, with dimensions of 287.6 × 270.4 × 198.2 km. [ 10 ] (523727) 2014 NW 65 is likely to be the second largest with 225 km (140 mi) and 2060 Chiron is likely to be the third largest ...

Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
