The research sheds light on ways in which aging stars can influence nearby planets, Penn State said in a news release. The discovered planet has a mass about six times that of Jupiter, the largest planet in the solar system that includes Earth, said Alexander Wolszczan from Penn State and Andrzej Niedzielski of Nicolaus Copernicus University.
