Vestibulure is the second gas giant of the Parumecaetes System. It is the last planet in the system and the most heavy of them all. Even when it is so far away from the other planets, it still protects them as a comet catcher. Comets who enter the system the side of the planet is are pulled towards the heavy mass of the gas giant. Even though this reduces the amount of comets in the system significantly, it still is not as good as a gas giant in one of the inner orbits.
