Uranus

Uranus is the seventh planet closest to the Sun in the solar system. It is the third largest planet in the solar system. It was discovered on March 13, 1781 by British astronomer William Herschel. The name Uranus is the Latin form of Uranus (Ουρανός, romanized Ouranos), the god of the sky in Greek mythology.

Because it has a maximum magnitude of +5.6, it can be seen with the naked eye at its closest approach. It was later discovered that it had been observed as a star more than 20 times (including with the naked eye) before Herschel. Of course, Herschel's achievement of confirming that it is a moving planet remains unchanged.
