Pamina (minor planet designation: 539 Pamina) is a minor planet orbiting the Sun in the main belt.[2] It is named for the heroine of Mozart's opera, The Magic Flute. This asteroid was discovered by M. Wolf in 1904 at the Heidelberg observatory in Germany.[3] It is orbiting at a distance of 2.74 astronomical unit|AU from the Sun, with an orbital eccentricity (ovalness) of 0.212 and a period of 4.53 yr. The orbital plane is inclined at an angle of 6.8° to the ecliptic.[1]
Photometric observations of this asteroid taken in 2004 provided a light curve showing a rotation period of 13.903±0.001 h with a brightness amplitude of 0.10±0.01 in magnitude. Infrared measurements give a diameter estimate of 54±3 km.[3]
