Uranus, discovered by Herschel in 1781. In March 1781, during his search for double stars, Herschel noticed an object appearing as a disk. Herschel originally thought it was a comet or a stellar disc, which he believed he might actually resolve. [40] He reported the sighting to Nevil Maskelyne the Astronomer Royal. [41]
The year 1781 in science and technology involved some significant events. ... March 13 – William Herschel observes Uranus (although initially recording it as a ...
Herschel discovered Uranus in 1781. Ejnar Hertzsprung: Denmark: 1873: 1967: He developed a classification system for stars to divide them by spectral type, stage in their development, and luminosity, the Hertzsprung–Russell diagram. Johannes Hevelius: Poland: 1611: 1687 Antony Hewish: United Kingdom: 1924: 2021
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 ...

Uranus orbits the Sun once every 84 years. As viewed against the background of stars, since being discovered in 1781, [66] the planet has returned to the point of its discovery northeast of the binary star Zeta Tauri twice—in March 1865 and March 1949—and will return to this location again in April 2033.

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 in 1781 William Herschel discovered a new planet, Uranus, [90] it was found it lies at a distance beyond Saturn that approximately matches that predicted by the Titius-Bode rule. That rule observed a gap between Mars and Jupiter void of any known planet.
