785 Zwetana is a minor planet orbiting the Sun that was discovered by Adam Massinger, an assistant at the Heidelberg Observatory, on March 30, 1914. Radar observations indicate that it is metallic.[citation needed]

In 1990, the asteroid was observed from the European Southern Observatory, allowing a composite light curve to be produced that showed a rotation period of 8.919 ± 0.004 hours and a brightness variation of 0.13 ± 0.01 in magnitude.[2]
