550 Senta is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on November 16, 1904 from Heidelberg.
Photometric observations of this asteroid made at the Torino Observatory in Italy during 1990–1991 were used to determine a synodic rotation period of 20.555 ± 0.01 hours.[2]
