Saturn’s moon Epimetheus discovered

Astronomer Richard Walker discovered Epimetheus, a moon of planet Saturn, on 18^th December 1966. The celestial object is named after the brother of Prometheus and is also known as Saturn XI. The moon was observed for the first time a few days back, on the 15^th of December, by French astronomer Audouin Dollfus, who named it Janus. However, Walker is generally credited to have made the discovery.
