HD 177830 is a 7th magnitude star located approximately 190 light-years away in the constellation of Lyra. It is slightly more massive than our Sun, but cooler being a type K star. Therefore it is a subgiant clearly more evolved than the Sun. In visual light it is four times brighter than the Sun, but because of its distance, about 190 light years, it is not visible to the unaided eye. With binoculars it should be easily visible.

  • HD 177830 is a 7th magnitude star located approximately 190 light-years away in the constellation of Lyra. It is slightly more massive than our Sun, but cooler being a type K star. Therefore it is a subgiant clearly more evolved than the Sun. In visual light it is four times brighter than the Sun, but because of its distance, about 190 light years, it is not visible to the unaided eye. With binoculars it should be easily visible. The star is known to have two extrasolar planets orbiting around it.
  • HD 177830 ist ein etwa 193 Lichtjahre von der Erde entfernter oranger Unterriese mit einer Rektaszension von 19h 05m 21s und einer Deklination von +25° 55' 14". Er besitzt eine scheinbare Helligkeit von 7,17 mag. Im Jahre 1997 entdeckte Steven S. Vogt einen extrasolaren Planeten, der diesen Stern umkreist. Dieser trägt den Namen HD 177830 b.
  • HD 177830 — звезда, которая находится в созвездии Лира на расстоянии около 192 световых лет от нас.
