Bode consulted older star charts and found numerous examples of the planet's position being given while being mistaken for a star, for example, John Flamsteed, Astronomer Royal in Britain, had listed it in his catalogue of 1690 as a ...

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.
