ケンタウルス族（太陽系の小天体）の一覧

以下はケンタウルス族の一覧である。ケンタウルス族は太陽系の非共鳴小天体のグループであり、その軌道は典型的には木星と海王星の軌道の間（5から30 AU）にある。ケンタウルス族は彗星の特徴を持つ小惑星であり、彗星として分類されることが多い。この力学的グループは、海王星の重力散乱によるカイパーベルトの侵食効果によって形成され、物体は内側に送られてケンタウルス族になるか、外側に送られて散乱円盤物体になるか、または太陽系から完全に除去される。ケンタウルス族自体は不安定な軌道を持ち、寿命が短く、数百万年以内にカイパーベルト天体の不活動集団から木星族彗星の活動グループに移行する。^[1]^[2]

ケンタウルス族のリストは、MPCのMPCORBデータファイル^[3]からJPL-SBDB ^[a]で定義された基準に基づいて編集され、ウィリアム・ジョンストンとマーク・ブイによる既知の太陽系外縁天体リスト^[4]と深黄道サーベイ天体分類^[5]の天体で補完されています。2022年4月現在、この表には928個の天体が含まれています。これらのソースごとに専用の列があり、天体がケンタウルス族であるかどうか（✓）またはそうでないかどうか（✗）を示しています。^[b]表では、赤と灰色のケンタウルス族が明確な背景色で強調表示されています（凡例を参照）。^[2]^[c]^[update]

Notes

^ a b The JPL Small-Body Database (SBDB), defines centaurs as "Objects with orbits between Jupiter and Neptune (5.5 au < a < 30.1 au)". Uranus and Neptune trojans are excluded if classified as such in the Johnston's Archive. A few unnumbered objects with a poorly determined obribt may be classified differently in the SBDB, as the orbital elements for this list are taken form the MPCORB data file directly. Chiron-type comets are only listed if included in the MPCORB data file.
^ Alternative classifications to centaur (CEN) include trans-Neptunian object (TNO), damocloid (DAM), unusual object (UMP), and resonant trans-Neptunian object, for example "3:2", for plutino). In addition, the classification of the Deep Ecliptic Survey divides centaurs into a R and S group (CENTAURR and CENTAURS).
^ An object's color ranges from BB to RR, split at a B–R magnitude of 1.45 into grey and red centaurs. Only for objects with a B–R color given in Johnston's Archive. Otherwise the table row is not highlighted.
^ A greyed-out table row contains an object with a perihelion (q, highlighted in red) that does not lie between the orbit of Jupiter and Neptune (5.1–30.1 AU), and is neither listed as centaur in Johnston's Archive nor in the Deep Ecliptic Survey classification (DES).
^ A bold designation links to an object's stand-alone article. In most other cases, a designation links to the corresponding entry in the list of minor planets or the list of unnumbered minor planets.
^ The discovery information is taken from MPC's List Of Centaurs and Scattered-Disk Objects or from a direct MPC Database Search.
^ An objects mean-diameter is given in kilometers and taken from Johnston's Archive. Otherwise, a calculated diameter is based on an estimated albedo of 0.09 and an absolute magnitude taken form the MPCORB data file.
^ The uncertainty parameter (U) indicates the quality of the current orbit determination (only displayed for unnumbered objects). In the Solar System Beyond Neptune classification (SSBN07) from 2007, an object is not a centaur, if it has a Jupiter tisserand (T_J) below 3.05 and a perihelion less than 7.35 AU. Additional physical properties such as the astronomical albedo, binary status, spectral type and B–R magnitude were taken from Johnston's archive.

[Grey-Red-Centaur-8] An object's color ranges from BB to RR, split at a B–R magnitude of 1.45 into grey and red centaurs. Only for objects with a B–R color given in Johnston's Archive. Otherwise the table row is not highlighted.

[Greyed-out-9] A greyed-out table row contains an object with a perihelion (q, highlighted in red) that does not lie between the orbit of Jupiter and Neptune (5.1–30.1 AU), and is neither listed as centaur in Johnston's Archive nor in the Deep Ecliptic Survey classification (DES).

[Diameter-13] An objects mean-diameter is given in kilometers and taken from Johnston's Archive. Otherwise, a calculated diameter is based on an estimated albedo of 0.09 and an absolute magnitude taken form the MPCORB data file.

[Remarks-14] The uncertainty parameter (U) indicates the quality of the current orbit determination (only displayed for unnumbered objects).
