Fraction of particles reaching a < 2 au, a < 1 au, and q < 0.005 au registered in Gladman et al. (1997); Bottke et al. (2002a); Todorović (2017) and this work.
| Gladman et al. (1997) | Bottke et al. (2002a) | Todorović (2017) | This work | |
|---|---|---|---|---|
| Number of particles | 146 | 359 | 1000 | 10080 |

| Ever have a < 2 au (%) | 1.4 | <6 | 25.3 | 19.86 |
| Ever have a < 1 au (%) | 0 | – | 23.4 | 9.43 |
| Ever have q < 0.005 au (%) | 7.5 | – | 7 | 27.4 |
| Ever have q < 0.00465 au (%) | – | – | – | 26.57 |
| Ever have q < 0.016 au (%) | – | – | – | 36.19 |
Notes. We also give the total number of particles and the integration time in all these studies. The last two rows represent our results for reaching q < 0.0465 au and q < 0.016 au (i.e. the fulfilment of criteria for Sun-diving and Sun-grazing objects according to the definition mentioned in Jones et al. 2018).
