Lightbulb Johann Elert Bode




Johann Elert Bode (19 January 1747 – 23 November 1826) was a German astronomer known for his reformulation and popularization of the Titius-Bode law. Bode determined the orbit of Uranus and suggested the planet's name...Bode was born in Hamburg. As a youth, he suffered from a serious eye disease which particularly damaged his right eye; he continued to have trouble with his eyes throughout his life...He began his career with the publication of a short work on the solar eclipse of 5 August 1766. This was followed by an elementary treatise on astronomy entitled Anleitung zur Kenntniss des gestirnten Himmels (1768, 10th ed. 1844), the success of which led to his being summoned to Berlin in 1772 for the purpose of computing ephemerides on an improved plan.



The Titius–Bode law (sometimes termed just Bode's law) is a hypothesis that the bodies in some orbital systems, including the Sun's, orbit at semi-major axes in a function of planetary sequence. The hypothesis correctly predicted the orbits of Ceres and Uranus, but failed as a predictor of Neptune's orbit...The discovery of Pluto in 1930 confounded the issue still further. While nowhere near its position as predicted by Bode's law, it was roughly at the position the law had predicted for Neptune. However, the subsequent discovery of the Kuiper belt, and in particular of the object Eris, which is larger than Pluto yet does not fit Bode's law, have further discredited the formula.
