Eccentric Jupiter

An eccentric Jupiter is a Jovian planet that orbits its star in an eccentric orbit. Eccentric Jupiters may probably disqualify a planetary system from having Earth-like planets in it because a massive gas giant with an eccentric orbit may remove all Earth mass planets from the habitable zone. To date, it appears that approximately 7% of all stars (half of the known planetary systems) have an eccentric Jupiter (e > 0.1), making these planets more common than Hot Jupiters. Out of the more than 200 extrasolar planet discoveries (as of 2006), 15 planets have high eccentricities (e > 0.6).
