編集凡例
編集- 惑星の質量について、地球質量 が判明している場合は 、地球半径 が判明している場合は を用いて木星質量 と木星半径 へ換算している。また、距離において単位が光年( )として判明している場合は を用いてパーセク( )へ換算している。換算された質量、半径、距離はそれぞれ小数第4位を四捨五入し、小数第3位まで記載する。
- 褐色矮星またはその可能性が高いもの(木星質量の13倍を目安とする)は記載していない。
- グリーゼ近傍恒星カタログでの表記はすべて「GJ」にしている。(例: グリーゼ581 → GJ 581)
- 発見方法の欄にある「RV」はドップラー分光法、「T」はトランジット法、「I」は直接観測法、「M」は重力マイクロレンズ法、「TTV」はTTV法、「I」は直接観測法、「A」はアストロメトリ法を表し、これら以外の発見方法は「O」で表す。
- 惑星の欄は予想される形態により以下の4色によって表されている。
