WASP-47 is a star similar in size and brightness to the Sun about 870 light-years away in the constellation Aquarius. It lies within the Kepler K2 campaign field 3. It was first noticed to have a hot Jupiter exoplanet orbiting every 4 days in 2012 by the Wide Angle Search for Planets (WASP) team. While it was thought to be a typical hot Jupiter system, three more planets were found in 2015: an outer gas giant within the habitable zone, a hot Neptune exterior to the hot Jupiter's orbit and a super-Earth interior to the hot Jupiter's orbit. WASP-47 is the only planetary system known to have both planets near the hot Jupiter and another planet much further out.

  • WASP-47 es similar al tamaño y al brillo del Sol a unos 650 años luz de distancia en la constelación de Acuario. Se encuentra dentro del campo 3 de la campaña Kepler K2. Primero se notó tener un exoplaneta de Júpiter caliente orbitando cada 4 días en 2012 por el equipo de Wide Angle Search for Planets (WASP). Si bien se pensaba que era un típico sistema de Júpiter caliente, se encontraron tres planetas más en 2015: un gigante de gas exterior dentro de la zona habitable, un Neptuno caliente y una megatierra. WASP-47 es el único sistema planetario que tiene ambos planetas cerca del Júpiter caliente y otro planeta mucho más alejado.​ (es)

  • WASP-47 — звезда, которая находится в созвездии Водолей на расстоянии приблизительно 652 световых лет от нас. Вокруг звезды обращаются, как минимум, четыре планеты. (ru)
  • WASP-47, autrement désignée K2-23 ou 2MASS J22044873-1201079, est un système multiplanétaire constitué d'au moins une étoile et quatre planètes. L'étoile du système est semblable en taille et en luminosité au Soleil, elle est située à environ ∼870 a.l. (∼267 pc) dans la direction de la constellation du Verseau. Le système se situe dans le troisième champ d'observation de la mission Kepler K2. En 2012 l'équipe du projet de recherche d'exoplanètes WASP détecte qu'une exoplanète de type Jupiter chaud gravite autour de l'étoile en bouclant sa révolution en 4 jours. Bien qu'on ait supposé au départ qu'il s'agissait d'un Jupiter chaud typique, trois autres planètes ont été découvertes en 2015 : une géante gazeuse extérieure située au sein de la zone habitable, un Neptune chaud et une méga-Terre.
