Detailed explanation-1: -When Uranus, the seventh planet from the Sun, was discovered in 1781, it expanded the known limits of our solar system. It was also the first planet to be discovered using a telescope, as Mercury, Venus, Mars, Jupiter and Saturn were all bright enough to be easily visible to the naked eye.

Detailed explanation-2: -∙ William Herschel is credited with the discovery of Uranus.

Detailed explanation-3: -The first planet to be discovered using a telescope was Uranus, which was recognized as a planet in 1781, based on telescope observations by Sir William Hershel (UK) and others. The observations that established Uranus as something other than a regular star were made on 13 March 1781 by Sir William Herschel.

Detailed explanation-4: -British astronomer William Herschel discovered Uranus on March 13, 1781, with his telescope while surveying all stars down to those about 10 times dimmer than can be seen by the naked eye. One star seemed different, and within a year Herschel realized the star followed a planetary orbit.

Detailed explanation-5: -In 1845, Urbain Le Verrier began his own independent research into Uranus’s orbit. On 23 September 1846, Johann Gottfried Galle located a new planet, later named Neptune, at nearly the position predicted by Le Verrier. The rotational period of the interior of Uranus is 17 hours, 14 minutes.
