Table 5
Number of the 91 125 clones of 2013 AZ60 simulated in this work that evolved to orbits with perihelion distances smaller than 2, 4, and 6 AU, and the number that evolved onto Earth-crossing orbits (following Horner et al. 2003).
| Number of clones | Percentage of total | |
| integration time | ||
|
|
||
| Earth-crossing | 3805 | 0.118 |
| (q< 1.0616 AU) | ||
| q< 2 AU | 6005 | 0.291 |
| q< 4 AU | 12 272 | 0.329 |
| q< 6 AU | 27 150 | 2.06 |
Notes. For each of these values, we also give the fraction of the total integration time, across all 91 125 clones, for which clones have perihelion distances within these limits. We note that this is the fraction of the time for which the perihelion distance was less than the stated amount and not the fraction of time the clones spend within that heliocentric distance. Even when moving on an orbit with a perihelion within that of the Earth, a given clone will spend the vast majority of its time beyond that distance, and only a tiny fraction within it.
