- •
We study the effects of radius, formation time and initial porosity on the thermo-mechanical evolution of planetesimals.
- •
Certain planetesimals retain shells of highly porous material.
- •
The long-term thermo-mechanical evolution is dominated by formation time and planetesimal size, rather than initial porosity.
