The discovery of five planets orbiting the star was announced October 2012. The planets are unusual in that they orbit near the parent star. The semi-major axis of the outermost planet is 1/12 the distance from Earth to the Sun. Radial velocity method could not be used to confirm the existence of planets due to star's faintness. Outermost two planets were confirmed through transit-timing variation method while it was not possible with inner planets due to relatively low signal-to-noise ratio. Two of the three other candidates were validated in February 2014. The remaining candidate is expected to be a real planet although its period is too short to validate through criteria given to confirm the planet.
