Eccentric Jupiter

An Eccentric Jupiter is a Jovian planet that orbits its star in a highly eccentric orbit, much like a comet. Eccentric Jupiters, like Hot Jupiters, are likely to disqualify a planetary system from having earth-like planets in it because a planet as massive as Jupiter can, given sufficient time, throw all planets of earth-like mass out of the system.

To date, it appears that approximately 7% of all stars have an Eccentric Jupiter planet, making these planets much more common than Hot Jupiters.
