Planetary system

In 2007, a planet of the star was announced by astronomer Simon J. O'Toole. The planet (designated HD 159868 b) is likely to be a gas giant. The orbit is extremely eccentric at the average distance of 2 astronomical units (AU), ranging as close as 0.62 AU to as far as 3.38 AU. During its orbital period, the planet spends most of its time in the habitable zone of its star.

In 2012, a second planet of the star was announced by astronomer Robert A. Wittenmyer.
