Wilhelm Tempel

Wilhelm Tempel was a German astronomer who is best known for his discovery of the comet 55P/Tempel-Tuttle on December 19, 1865. This periodic comet is the source of the Leonid meteor shower, which occurs annually when Earth passes through the debris left by the comet. Tempel's contributions to astronomy include his observations and studies of various comets and celestial phenomena during the 19th century.
