HIP 11915 is a G-type main-sequence star located about 190 light-years from Earth in the constellation Cetus. It is best known for its characteristics, which are very similar to those of the Sun, including the mass, radius, temperature, metallicity and age, which means that it is almost a solar twin, being just 500 million years younger than the Sun and with a lower metallicity. It is also known for its planetary companion, HIP 11915 b, which has a mass and orbital distance very similar to that of Jupiter, but probably with a slightly higher orbital eccentricity.

  • HIP 11915, aussi connu en tant que HD 16008, est un système planétaire situé dans la constellation de la Baleine. L'objet primaire de ce système est une étoile naine jaune. Le système abrite au moins une planète, HIP 11915 b, dont la masse et la distance à son étoile la rendent très similaire à Jupiter dans le système solaire. (fr)
  • HIP 11915 è una stella di tipo G (nana gialla) analoga al Sole situata a 175 anni luce di distanza dalla Terra nella costellazione della Balena. La designazione deriva dal numero assegnato (11915) nel catalogo Hipparcos La sua luce è fievole perché questa possa essere vista ad occhio nudo, ma rimane comunque visibile con un buon binocolo.. La massa e le dimensioni sono circa le stesse della nostra stella, e la temperatura di pochi gradi inferiore (5760 K, così come leggermente inferiore è la metallicità, dell'87% di quella del Sole. Queste caratteristiche ne fanno una delle migliori candidate per essere considerata gemella del Sole. (it)
  • HIP 11915 är en sollik stjärna i Valfiskens stjärnbild. Runt den har en planet av Jupiters storlek upptäckts, på nästan exakt samma avstånd från sin stjärna som Jupiter. HIP 11915 har samma massa och är ungefär lika gammal som solen. (sv)
  • HIP 11915 é Uma estrela pertencente à constelação da Baleia, semelhante ao sol em termos de idade, massa, e composição química, distante aproximadamente 186 anos luz do sistema solar. (pt)
  • HIP 11915是一顆距離地球約186光年的黃矮星,在天球上位於鯨魚座。該恆星為類太陽恆星,必須以望遠鏡觀測。 (zh)
  • HIP 11915 ist ein Gelber Zwerg im Sternbild Walfisch, der rund 186 Lichtjahre von der Sonne entfernt ist. Er weist eine der Sonne annähernd gleichende Masse, Temperatur, und Metallizität sowie ein vergleichbares Alter auf und ist daher ein sogenannter „Solar twin“ (engl. Sonnenzwilling). 2015 wurde die Entdeckung eines annähernd jupitergroßen Exoplaneten um den Stern bekanntgegeben, der HIP 11915 in etwa der gleichen Entfernung umkreist wie Jupiter die Sonne. (de)

  • HIP 11915 (также известная как HD 16008)— звезда северного созвездия Кита. Имея видимую звёздную величину 8,58m, звезда невидима невооружённым глазом, но может наблюдаться в хороший бинокль. Она находится на расстоянии 190 св. лет (57 пк) от Земли и является одним из ближайших близнецов Солнца. Она очень похожа на наше Солнце, в том числе по массе, радиусу, температуре, будучи всего на 500 миллионов лет моложе Солнца и имея более низкую металличность. (ru)
