Main-belt asteroid
From Wikipedia, the free encyclopedia
549 Jessonda is a minor planet orbiting the Sun. According to the Catalogue of Minor Planet Names and Discovery Circumstances, it is "named presumably after the character in the opera of the same name by the German composer, conductor and violinist Ludwig Spohr (1784–1859), one of the leading composers in the early romantic period.'[2] (Around 1904 Max Wolf named numerous asteroids he had discovered after female characters in opera.)
