HD 181433 is a star located approximately 87 light-years away in the constellation of Pavo (the Peacock). According to SIMBAD, it has a stellar classification of K3III-IV, which puts it on the borderline between being a red giant and a subgiant. This is inconsistent with the fact that its luminosity is only 0.308 times that of the Sun. Its entry in the Hipparcos catalogue lists a spectral type of K5V, classifying it as a dwarf star. As of 2008, three extrasolar planets are thought to be orbiting the star. There is currently little information on these planets. The name of this star comes from its identifier in the Henry Draper catalogue.

  • HD 181433 is een ster in het sterrenbeeld Pauw (Pavo). De ster is een oranje dwerg en heeft drie bevestigde exoplaneten. De ster is net iets kleiner dan de Zon en ligt op een afstand van 88,03 lichtjaar. (nl)
  • HD 181433 è una stella localizzata a 88 anni luce dalla Terra, nella costellazione del Pavone. Nel database stellare SIMBAD la stella è classificata come di tipo spettrale K3III-IV, il che la pone ai confini tra una gigante arancione ed una subgigante. Tuttavia, avendo una luminosità pari a 0,37 volte quella del nostro Sole, non sembrerebbe una stella uscita dalla sequenza principale, ed infatti il catalogo Hipparcos e altri la classificano di tipo K5V, cioè come nana arancione. Nel 2008 sono stati scoperti tre pianeti extrasolari orbitanti attorno alla stella. (it)
  • HD 181433 – gwiazda pojedyncza oddalona od Ziemi o ok. 85 lat świetlnych, położona w gwiazdozbiorze Pawia. Według bazy danych SIMBAD typ widmowy tej gwiazdy to K3 III-IV, co stawiałoby ją na pograniczu olbrzymów i podolbrzymów, podczas gdy według katalogu Hipparcosa ma ona typ widmowy K5 V, co wskazywałoby, że jest ona karłem. W czerwcu 2008 ogłoszono odkrycie dwóch, a w grudniu trzeciej planety orbitującej wokół tej gwiazdy. Na razie niewiele o nich wiadomo. Planeta położona bliżej gwiazdy ma masę zaledwie 7,6 masy Ziemi i jest zapewne wielką planetą skalistą – tzw. superziemią. (pl)
  • HD 181433 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Påfågeln. Den har en skenbar magnitud av ca 8,38 och kräver åtminstone en stark handkikare eller ett mindre teleskop för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 37,4 mas, beräknas den befinna sig på ett avstånd på ca 87 ljusår (ca 27 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 38 km/s. (sv)
  • HD 181433 — звезда в созвездии Павлина. Находится на расстоянии около 87 световых лет от Солнца. Вокруг звезды обращаются три (неподтверждённые) планеты. Имеет видимую звёздную величину +8,38m. (ru)
  • HD 181433是一颗距离地球大约87光年的恒星,位于孔雀座。根据SIMBAD的记载,它的分类为K3III-IV,这说明它处于红巨星和亚巨星的交界区。而这与它的光度性质是不符合的,因为它的光度只有太阳的0.308倍。它在依巴谷星表中列出的光谱类型是K5V,也就是一颗矮星。截至2008年,已发现三颗太阳系外行星围绕它公转。现在我们对那些星系了解甚少。这颗恒星的名称来自于它在亨利·德雷伯星表中的编号。 (zh)
