134 Sophrosyne 134 Sophrosyne Sophrosyne (minor planet designation: 134 Sophrosyne) is a large main-belt asteroid that was discovered by German astronomer Robert Luther on September 27, 1873, and was named after the concept of "sophrosyne", Plato's term for 'moderation'.

An occultation of a star by 134 Sophrosyne was observed November 24, 1980, in the United States. Timing information from this event allowed a diameter estimate of 110 km to be derived. Photometric observations of the asteroid in 2015 produced a lightcurve indicating a rotation
Ancient Greek phonology to the ones that occurred later in Koine. This section primarily describes sound changes that occurred between the Mycenaean and Ancient Greek periods and during the Ancient Greek period. For sound changes occurring in Proto-Greek and in Koine Greek, see and Koine Greek phonology. In Proto-Greek, the PIE sibilant became by debuccalization in many cases.
