(58734) Jeantarde Main-belt Asteroid
Discovered on 2 March 1998 by ODAS at Caussols.
Jean Tarde (c. 1561–1636) was a French ecclesiastic and astronomer born in La Roque-Gageac. A supporter of heliocentrism, he studied sunspots for 10 years with a telescope lent by Galileo. Since Jean believed that the Sun was pure, he espoused the idea that sunspots were small planets orbiting close to the Sun, which he called “Bourbon's planets”.Naming citation (WGSBN Bull. 5, #19, 5), IAU / Minor Planet Center, via NASA/JPL
