(26) Proserpina is an asteroid of the main belt that was discovered on May 5, 1853 by Karl Theodor Robert Luther at the Düsseldorf observatory .
The celestial body was named after Proserpina , the daughter of the Roman goddess Ceres and Jupiter . She was the wife of Pluton , the Roman god of the underworld.
Proserpina moves at a distance of 2.4 ( perihelion ) to 2.9 ( aphelion ) astronomical units on an almost circular orbit around the sun . The orbit is inclined 3.6 ° to the ecliptic , the orbital eccentricity is 0.09.
Proserpina has a diameter of 95 kilometers.
Just as there was a Greek mythological Persephone corresponding to the Roman Proserpine, there is also an asteroid called Persephone .
