Density of the comet: ρc = 1.10g/cm3
Density of Saturn: ρS = 0.690g/cm3
rR = 2.44(ρs/ρc)1/3R
R = radius of Saturn = 60,330 km
rR = 2.44(0.690/1.10)1/3 x 60, 300
0.690/1.10 = 0.62721
1/3(log0.6272) = -(0.20259/3) = - 0.06753
(0.690/1.10)1/3 = 0.8559
rR = 2.44 x 0.8559 x 60, 330 = 125,993km
rR = 125,993
