The radius of Venus has been determined from radar-range data taken at the Jet Propulsion Laboratory's Goldstone facility. A simultaneous intergration of the equations of motion of the solar-system fit to this time-delay data gave a value of 6053.7 ± 2.2 kilometers. A discussion of other Venusian radius determinations is made.
