This planet is probably slightly less massive than [[Jupiter]]. It is an "[[eccentricity (orbit)|eccentric]] Jupiter" meaning that it does not orbit very near the star like the famous [[51 Pegasi b]] but further out and its orbit is very oval-shaped. The mean distance from the star is 2.11 [[astronomical unit|AU]], about twice the [[Earth|Earth's]] distance from the Sun. At [[periastron]], the planet is only 1.43 AU from the star (comparable to the distance of [[Mars]] from the Sun), and at [[apoastron]], the orbital distance is 2.72 AU (inner [[asteroid belt]]).<ref name="Butler2006"/>
