Property Value
dbo:abstract K2 229 est un système planétaire de la constellation zodiacale de la Vierge constitué d'une étoile naine orange et de plusieurs planètes en transit. Il est distant d'environ ∼335 a.l. (∼103 pc) de la Terre. (fr) K2-229 (also designated EPIC 228801451 or TYC 4947-834-1) is a K-type main sequence star approximately 103 parsecs (335 light years) away in the constellation Virgo. It was observed by the Kepler Space Telescope during its K2 "Second Light" mission in Campaign 10. (en) K2-229(EPIC 228801451やTYC 4947-834-1とも呼ばれる)とは、地球からおとめ座の方向に約103パーセク(335光年)離れたところに存在するスペクトル分類がK型の主系列星である。キャンペーン10のK2「セカンドライト」のミッション中にケプラー宇宙望遠鏡によって観測され、3つの太陽系外惑星が周囲を公転していることが確認されている。 (ja) K2-229 è una stella nana arancione situata a circa 340 anni luce dalla Terra, nella costellazione della Vergine. Attorno ad essa, nel 2018, tramite la missione estesa del telescopio spaziale Kepler sono stati scoperti tre pianeti extrasolari. (it)
