HD 231701 b is an extrasolar planet approximately 354 light years away in the constellation of Sagitta. This planet orbits at 0.55 AU from the star HD 231701 with eccentricity 0.19. Based on its high mass of 1.08 M_J, the planet is probably a gas giant, meaning the planet has no solid surface and have composition similar to solar system's outer planets.
