[1] [5] [10] In the subgenre of works visiting multiple locations in the Solar System that appeared throughout the 19th century, Uranus was rarely included, [1] one exception being the anonymously published 1837 novel Journeys into the Moon, Several Planets and the Sun. [2] Early works about Uranus incorrectly envisioned it as a solid planet.
The three men also visited the astronomer William Herschel at Slough, who had discovered Uranus in 1781. With his surveying skills, Méchain worked on maps of Northern Italy and Germany after this, but his most important mapping work was geodetic : the determination of the southern part of the meridian arc of the Earth 's surface between ...

1781 – Charles Messier and his assistant Pierre Méchain publish the first catalogue of 110 nebulae and star clusters, the most prominent deep-sky objects that can easily be observed from Earth's Northern Hemisphere, in order not to be confused with ordinary Solar System's comets.

In 1781, William Herschel was looking for binary stars in the constellation of Taurus when he observed what he thought was a new comet. Its orbit revealed that it was a new planet, Uranus, the first ever discovered telescopically. [20] Giuseppe Piazzi discovered Ceres in 1801, a small world between Mars and
When William Herschel discovered Uranus in 1781, he at first named it Georgium Sidus (George's Star) after the King, who later funded the construction and maintenance of Herschel's 1785 40-foot telescope, which at the time was the biggest ever built.
