Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An extrasolar planet is a planet located outside the Solar System. As of 22 January 2011, astronomers have announced confirmed detections of 519 such planets. This is a list of the most notable discoveries. Gamma Cephei Ab: The radial velocity variations of the star Gamma Cephei were announced in 1989, consistent with a planet in a 2.5-year orbit. However misclassification of the star as a giant combined with an underestimation of the orbit of the Gamma Cephei binary, which implied the planet's orbit would be unstable, led some astronomers to suspect the variations were merely due to stellar rotation. The existence of the planet was finally confirmed in 2002.show more
