Impact probabilities with the planets for different simulation sets.
| Planet Unit | PP [GPU C] % | Penc [GPU C] % | PP [RMVS C] % | PP [GPU M] % | Penc [GPU M] % | PP [RMVS M] % |
|---|---|---|---|---|---|---|
| Jupiter | 0.29 | 15.6 | 0.37 | 0.78 | 33 | 1.2 |
| Saturn | 0.12 | 5.9 | 0.13 | 0.28 | 14 | 0.46 |
| Uranus | 0.059 | 3.4 | 0.071 | 0.56 | 19 | 0.19 |
Notes. Here we list the impact and encounter probabilities, averaged for the various simulations. The C stands for the clone simulations, run for the last 3.5 Gyr, while M stands for the migration simulations, which were run either for 200 Myr (GPU) or 4.5 Gyr (RMVS). The impact probability of planetesimals with the planets during flyby is 1.6% for Uranus, 1.9% for Saturn, and 2.1% for Jupiter, close to the theoretical 2.5%. Uncertainties are listed in the Supplementary Materials on Zenodo.
