Kepler-7 (original) (raw)
Kepler-7 ist ein Stern vom späten F- oder frühen G-Typ, der von einem Exoplaneten mit der Bezeichnung Kepler-7b begleitet wird. Der Stern scheint nahe dem Ende seiner Lebensdauer auf der Hauptreihe zu sein; bei einer Masse von ca. 1,3 Sonnenmassen hat sich sein Radius auf 1,8 Sonnenradien ausgedehnt.

| dbo:abstract | Kepler-7 ist ein Stern vom späten F- oder frühen G-Typ, der von einem Exoplaneten mit der Bezeichnung Kepler-7b begleitet wird. Der Stern scheint nahe dem Ende seiner Lebensdauer auf der Hauptreihe zu sein; bei einer Masse von ca. 1,3 Sonnenmassen hat sich sein Radius auf 1,8 Sonnenradien ausgedehnt. (de) Kepler-7 is a star located in the constellation Lyra in the field of view of the Kepler Mission, a NASA operation in search of Earth-like planets. It is home to the fourth of the first five planets that Kepler discovered; this planet, a Jupiter-size gas giant named Kepler-7b, is as light as styrofoam. The star itself is more massive than the Sun, and is nearly twice the Sun's radius. It is also slightly metal-rich, a major factor in the formation of planetary systems. Kepler-7's planet was presented on January 4, 2010 at a meeting of the American Astronomical Society. (en) Kepler-7 est une étoile dans la constellation de la Lyre, distante d'environ ∼3 000 a.l. (∼920 pc) de la Terre. C'est une étoile jaune de type spectral G0 sujette à des éruptions. (fr) Kepler-7 è una stella nana gialla visibile nella costellazione della Lira. Il 4 gennaio è stata illustrata all'American Astronomical Society la scoperta di un esopianeta orbitante attorno alla stella, tramite il satellite Kepler. I primi 5 pianeti extrasolari scoperti con la Missione Keplero. (it) ケプラー7 (英: Kepler-7) は、こと座の方角の、NASAが太陽系外惑星探査を行う宇宙望遠鏡ケプラーの観測領域内に位置する恒星である。ケプラーによる発見が最初に公表された5つの系外惑星の内の1つの母星であり、太陽よりも大きく、金属量は太陽より少し多い。2010年1月4日、ケプラー7の周囲を公転する太陽系外惑星の存在は、アメリカ天文学会の会合で公表された。 (ja) 케플러-7은 지구에서 바라볼 때 거문고자리 방향에 위치해 있는 항성이다. 이 별은 케플러 계획의 탐사 대상이다. (ko) Kepler-7 is een ster in het sterrenbeeld Lier (Lyra). De ster is van het type G en heeft één bevestigde exoplaneet. De ster is groter dan de Zon en ligt op een afstand van 3090 lichtjaar. (nl) Kepler-7 é uma estrela localizada na constelação de Lyra no campo de visão da Missão Kepler, da NASA uma operação em busca de planetas semelhantes à Terra. É o lar do quarto ou dos cinco primeiros planetas que Kepler descobriu; este planeta, um gigante gasoso do tamanho de Júpiter chamado Kepler-7b, é leve como isopor. A estrela em si é mais massiva que o Sol, e é quase duas vezes o raio do Sol. Também é ligeiramente rica em metais, um fator importante na formação de sistemas planetários. O planeta de Kepler-7 foi apresentado em 4 de janeiro de 2010 em uma reunião da American Astronomical Society. (pt) 开普勒7（英語：Kepler-7），是一颗位于天琴座的恒星。這顆恆星是由开普勒太空望远镜發現的，是該望远镜發現的第7個恆星。於2010年，开普勒太空望远镜发现它的一颗行星开普勒7b。這個行星是开普勒太空望远镜發現的第四個行星，該行星是一個氣體巨行星，其規模比木星還要大，但密度卻與土星相近。开普勒7比太陽質量還要大，且其半徑接近太陽半徑的兩倍。這颗恆星亦擁有很高的金屬量，而這直接影響了开普勒7行星系的形成。美國航空航天局於2010年1月4日在美國天文學會會議上發佈這個發現。 (zh) Kepler-7 — звезда в созвездии Лиры.
