937 Bethgea is an S or R-type asteroid belonging to the Flora family in the Main Belt. It was discovered by German astronomer Karl Wilhelm Reinmuth on September 12, 1920 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 8.356 ± 0.006 hours.[2][3]
