曖昧さ回避 この項目では、2つ以上の太陽系外惑星を持つ惑星系について説明しています。全ての太陽系外惑星の一覧については「太陽系外惑星の一覧」をご覧ください。
2014年10月26日までに発見された各年の太陽系外惑星の発見数。

本稿では、複数惑星系の一覧について取り上げる。複数個の惑星を持つ惑星系は特に複数惑星系[1][2][3]（英語: Multiple planetary system[1]、Multiplanetary system）または多重惑星系[4][5]と呼ばれる。NASA Exoplanet Archive の統計によると、2024年12月1日時点で太陽系外惑星が確認されている4,321個の恒星のうち2個以上の惑星が確認されている複数惑星系は969個である[6]。既知の惑星系内における惑星数の最多記録は太陽系とケプラー90系の8個で、TRAPPIST-1系の7個がこれに次ぐ。

一覧

[編集]

一覧は3個以上の惑星がある事が知られている、もしくは2個の惑星と1個以上の未確認の惑星候補が存在している可能性がある複数惑星系を地球からの距離が近い順に並べている。最も近いのは2個の確実な惑星と1個の未確認の惑星を持つことが知られているプロキシマ・ケンタウリ系である（近い恒星の一覧も参照）。しかし、ほとんどの複数惑星系は地球から非常に遠い位置にあり、一番遠いとされている複数惑星系は13,300光年離れた位置にあるOGLE-2012-BLG-0026L系であるとされている。

恒星の赤経、赤緯、距離（ガイア計画[7]による観測などから求められた年周視差より計算）はSIMBADのデータに基づく。視等級は特記しない限り、可視光線で観測されるVバンドでの等級を示すが、それ以外の波長域のバンドによる等級の場合はそのバンド名を括弧付きで付している。

  1. ^ HD 133131 系は HD 133131 A と HD 133131 B の2つの恒星から成る連星系であり、前者には2つの惑星、後者には1つの惑星が周囲を公転していることが知られている。ここでは HD 133131 系全体の総数として惑星を3個持つものとして扱う。
  2. ^ NASA Exoplanet Archive では1個の惑星（K2-302b）と1個の惑星候補（EPIC 206215704.01）が存在していると扱われているが[159]、太陽系外惑星エンサイクロペディアでは3個目の惑星（K2-302b、c、d）が確認済みとして扱われている[160]。
  3. ^ XO-2系は XO-2A (XO-2S) と XO-2B (XO-2N) の2つの恒星から成る連星系であり、前者には3つの惑星、後者には1つの惑星が周囲を公転していることが知られている。ここでは XO-2 系全体の総数として惑星を4個持つものとして扱う。
  4. ^ a b この惑星系の惑星は、複数の恒星から成る連星全体を公転している周連星惑星であることが知られている。ここでは主星である連星のうち、質量が大きい方の恒星の質量・有効温度・年齢のみを表示している。
  5. ^ NASA Exoplanet Archive では5個の惑星（ケプラー154b、c、d、e、f）と1個の惑星候補（KOI-435.02）が存在していると扱われているが[218]、太陽系外惑星エンサイクロペディアでは2020年に公表された研究で報告された6個目の惑星（ケプラー154g）も確認済みとして扱われている[219]。このケプラー154gと KOI-435.02 が同一の惑星であるかは研究内では言及されていないが[217]、ここでは両者を区別して6個の惑星と1個の惑星候補を持つ惑星系として扱う。
