First Planet Discovered By telescope

Out of the nine(sometimes 10) planets in our solar system only 3 of them have been officially discovered. The rest  are observable, unaided, by our  the naked eyes.

It wasn’t until the late 18th century, however, that an astronomer chanced upon a planetary body that had never been observed before. In 1781 Sir William Herschel–not only a famed astronomer but talented musician and prolific composer–was the first Human to gaze upon the far away planet of Uranus and, in doing so, became the first person a live  to officially discover a planet in our  enermous solar system. 

For the curious, the other discovered planets are Neptune  by John Couch Adams discoverd in 1846  and Pluto discovered in Clyde Tombaugh in 1930.
