We investigate the solar Type III radio bursts recorded at about 10 AU by Cassini spacecraft. More than 300 bursts have been recorded by the RPWS experiment in the time interval from 01 Jan. 2008 to 31 Dec. 2014. We show that the solar Type III occurrence is mainly depending on the solar activity and also exhibits maxima and minima of detection. The source location of such solar bursts is the interplanetary medium because the dominant emission appears at frequency lower than 2.3 MHz.
