http://www.msnbc.com/news/934038.asp Its similar in that the "Jupiter-like" planet they've viewed in this case is caught in a circular orbit. Most of the planets found in other star systems are in the oval shaped orbit. The oval orbit of large planets tends to wack the smaller ones out of the system. In this case there is a chance that an "earth-like" planet has remained in the system due to the circular orbit of the "Jupiter-like" planet. Check it out! Thanks.
