Gliese 3634 (Often shortened to GJ 3634) is a red dwarf star in the Hydra constellation. One planet has been discovered in its orbit, Gliese 3634 b. GJ 3634 is under half the mass and size of the Sun, and is estimated to be at least a billion years younger, and lies near to Earth, with a distance of 19.8 parsecs (64.6 light years). It was targeted by astronomers during an over six-year survey of red dwarfs. The astronomers had recently changed their strategy to search for planets with extremely short orbits so they could narrow down candidates that transited, or crossed in front of, their host stars as seen from the Earth. The Super-Earth GJ 3634 b was the first planet discovered using this new strategy. The planet was confirmed using Doppler spectroscopy, or the observation and extrapolat

  • GJ 3634 est une naine rouge située à environ ∼66,5 a.l. (∼20,4 pc) de la Terre dans la constellation de l'Hydre. Une planète a été découverte dans son orbite, GJ 3634 b. Celle-ci a environ la moitié de la masse et de la taille du Soleil, pour un âge d'environ un milliard d'années plus jeune. Elle a été découverte par des astronomes durant un recensement de naines rouges. (fr)
  • GJ 3634 — звезда, которая находится в созвездии Гидры на расстоянии приблизительно 64 световых лет от нас. Вокруг звезды обращается, как минимум, одна планета. (ru)
  • GJ 3634是长蛇座的一颗红矮星。其轨道上已发现一颗行星GJ 3634 b。GJ 3634的大小和质量比太阳的一半还小,据估计至少比太阳年輕10億年,距地球19.8秒差距(64.6光年)。它是一众天文学家长达6年多时间里的观测对象。 (zh)
  • GJ 3634 (LHS 2335 / LP 905-36)​ es una estrella de magnitud aparente +11,93.Desde 2011 se conoce la existencia de un planeta extrasolar en órbita alrededor de esta estrella. GJ 3634 está situada a 65,5 años luz del Sistema Solar en dirección a la constelación de Hidra.Es una enana roja de tipo espectral M2.5.​Mucho menos luminosa que el Sol, su luminosidad apenas alcanza el 2% de la luminosidad solar.Tiene una masa de 0,45 masas solares y no existe consenso en cuanto a su metalicidad (abundancia relativa de elementos más pesados que el helio); diversos estudios sitúan su índice de metalicidad entre -0,10 y +0,15.Asumiendo una metalicidad igual a la solar y una edad de 5000 millones de años, se puede estimar su radio, aproximadamente igual al 43% del radio solar.Su cinemática indica una eda (es)

  • Gliese 3634 (também conhecida como GJ 3634) é uma estrela anã vermelha localizada na constelação de Hydra. Um planeta foi descoberto em sua órbita, Gliese 3634 b. GJ 3634 tem metade da massa e tamanho do Sol, e está estimada a ser pelo menos um bilhão de anos mais jovem, e está próxima da Terra, a uma distância de 19,8 parsecs (64,6 anos-luz). Foi alvo de astrônomos durante uma pesquisa de mais de seis anos sobre anãs vermelhas. Os astrônomos recentemente tiveram que mudar suas estratégias para procurar por planetas com órbitas extremamente curtas para que eles pudessem diminuir os candidatos que transitavam ou cruzavam em frente das estrelas hospedeiras como visto da Terra. A superterra GJ 3634 b foi o primeiro planeta descoberto usando esta nova estratégia. O planeta foi confirmado usand (pt)
