This artist's concept depicts a giant planet orbiting the star 51 Pegasi, in the constellation Pegasus. The planet was the first found orbiting another Sun-like star, in 1995. Since then, astronomers have discovered almost 2,000 confirmed planets in other star systems, with several thousand more awaiting confirmation. [ESO/M. Kornmesser/Nick Risinger (skysurvey.org)]
