174 Phaedra is a sizable, rocky main belt asteroid that was discovered by Canadian-American astronomer James Craig Watson on September 2, 1877, and named after Phaedra, the tragic lovelorn queen in Greek mythology.
Lightcurve data obtained from Phaedra indicates a rather irregular or elongated body.
Photometric observations of this asteroid at the Shadowbox Observatory in Carmel, Indiana, during 2009 gave a light curve with a period of 4.96 ± 0.01 hours. This is consistent with previous studies in 1977, 1988, and 2008.[2]
