Template:Short description Template:Use dmy dates Template:Infobox planet
134 Sophrosyne is a large main-belt asteroid that was discovered by German astronomer Robert Luther on 27 September 1873, and was named after the concept of sophrosyne, Plato's term for 'moderation'. Classified as a C-type asteroid, it has an exceedingly dark surface and most probably a primitive carbonaceous composition.Template:Citation needed
An occultation of a star by 134 Sophrosyne was observed 24 November 1980, in the United States. Timing information from this event allowed a diameter estimate of 110 km to be derived.<ref name="Taylor1983"/> Photometric observations of the asteroid in 2015 produced a lightcurve indicating a rotation period of Template:Val with a variation amplitude of Template:Val in magnitude. This provided a good match to the only previous determination in 1989.<ref name=Pilcher2015/>
