Binned distributions Mj of semimajor axes a and inclinations i of synthetic NEO orbits, originating from individual asteroid families. The colors correspond to the number of test particles in bins, although the quantity Mj(a, i) was eventually normalized. The bin sizes were 0.01 au and 1°, respectively. The Apophis orbit is marked with a black cross. The orbits of other LL-like NEOs from Binzel et al. (2019); Marsset et al. (2022) are marked with gray crosses. Of the three, the highest density for producing Apophis-like objects is from the Flora family.
