HD 173416 b is an extrasolar planet located approximately 440 light years away in the constellation of Lyra, orbiting the 6th magnitude G-type giant star HD 173416. This is a superjovian planet discovered on January 10, 2009 by Liu et al. This planet orbits at 1.16 AU from the star. However despite the fact that the planet orbits 16% further from the star than Earth does from the Sun, it has orbital period of only 323.6 days, compared to 365.25 days for Earth.

dbpprop:abstract
  • HD 173416 b is an extrasolar planet located approximately 440 light years away in the constellation of Lyra, orbiting the 6th magnitude G-type giant star HD 173416. This is a superjovian planet discovered on January 10, 2009 by Liu et al. This planet orbits at 1.16 AU from the star. However despite the fact that the planet orbits 16% further from the star than Earth does from the Sun, it has orbital period of only 323.6 days, compared to 365.25 days for Earth. This inverse relationship is caused by the parent star having twice the mass of our Sun, which increases the strength of its gravitional field. This evidence implies that when this star was on the main sequence, it was an A-type star.
