Planetary system

In April 2000, a planet was discovered using radial velocity measurements taken at Fred Lawrence Whipple Observatory and Lick Observatory. The orbital parameters were updated in 2006 and 2007 using additional measurements. A second planet with a much longer period was discovered in 2019.
