471 Papagena is an asteroid that was discovered by German astronomer Max Wolf on June 7, 1901.[1] Its provisional name was 1901 GN.
Papagena comes to a favorable near-opposition apparent magnitude of better than magnitude 9.8 every five years. On September 30, 2010, it will be magnitude 9.68 and will get brighter every five years until December 12, 2035, when this late-to-be-discovered asteroid will be at magnitude 9.28. It is named for a character in Mozart's opera, The Magic Flute.
