2D collision probability between a dust particle of radius s (x-axis, in centimeters) and a planetesimal of radius Rp (y-axis, in kilometers), calculated for the MMSN at 1AU, physical densities , a turbulence parameter α = 10-2, and the eccentricity distribution shown in Fig. 2. The values of range from 10-12 (inefficient) to close to 1 (perfect). We note that given the assumed value, a 0.1 M (resp. 1) embryo is equivalent to a planetesimal with Rp = 5225 km (resp. 11250 km).
