Actually, William Herschel, who discovered Uranus and thus fractured the classical structure of five (Pythagorean) planets, initially thought it was a comet and wanted to call it George after his (adopted) king.
"As the most renowned astronomer of his time, William Herschel contributed significantly to most branches of astronomy. Besides searching clusters and nebulae, he discovered the planet Uranus in 1781, two satellites of Uranus, Titania and Oberon, in 1787, and Saturn's moons Mimas and Enceladus in 1789. He investigated the proper motion of stars and derived the peculiar motion of the solar system toward the direction of constellation Hercules, modelled the Milky Way galaxy from stellar statistics, and speculated about the nature of the nebulae, including a discussion of the possibility of external island universes (galaxies) which had been brought up by Kant. He also contributed to physics (especially optics) and, e.g., discovered the infrared light."
Herschel, a titan of his time, though almost certainly no relative of Tamburlane, is however linked to others.
