Johann Elert Bode (German: [ˈboːdə]; 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.
His early promise in mathematics brought him to the attention of Johann Georg Büsch, who allowed Bode to use his own library for study. 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 invited to Berlin by Johann Heinrich Lambert in 1772 for the purpose of computing ephemerides on an improved plan. There he founded, in 1774, the well-known Astronomisches Jahrbuch, 51 yearly volumes of which he compiled and issued.
He became director of the Berlin Observatory in 1786, from which he retired in 1825. There he published the Uranographia in 1801, a celestial atlas that aimed both at scientific accuracy in showing the positions of stars and other astronomical objects, as well as the artistic interpretation of the stellar constellation figures. The Uranographia marks the climax of an epoch of artistic representation of the constellations. Later atlases showed fewer and fewer elaborate figures until they were no longer printed on such tables.
Bode also published another small star atlas, intended for astronomical amateurs (Vorstellung der Gestirne). He is credited with the discovery of Bode's Galaxy (M81). Comet Bode (C/1779 A1) is named after him; its orbit was calculated by Erik Prosperin. Asteroid 998 Bodea, discovered 1923 August 6 by Karl Reinmuth at Heidelberg, was also christened in his honour, the letter 'a' added to its name to fulfil the convention that asteroids were given feminine names.
