Papagena (minor planet designation: 471 Papagena) is an asteroid that was discovered by German astronomer Max Wolf on 7 June 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 30 September 2010, it was magnitude 9.68 and it will get brighter every five years until 12 December 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.[citation needed]
