TL;DR: In this article, it was estimated that the radius of Icarus is between 0.3 and 0.6 kilometres and the rotation period between 1.5 and 3.3 hours.
Abstract: Radar observations of Icarus were made in mid-June 1968, at the time of closest approach. From the data, it is estimated that the radius is between 0.3 and 0.6 kilometer and the rotation period between 1.5 and 3.3 hours. A set of round-trip Doppler shift measurements is given.
