range -7,000 to +1,000 yr. The orbital behaviour on longer time-scales, even if not coincident, can also be discussed but in probabilistic terms. For example, 100% of the control orbits go from the $L_4$ Lagrangian point into the quasi-satellite phase but that transition takes place in the time frame 8,000-7,000 yr into the past for 70% of the control orbits with the remaining 30% experiencing the transition earlier than 8,000 yr ago. Prior to the $L_4$ Trojan state, 60% of control calculations were following horseshoe orbits, 20% were in the quasi-satellite state, 10% were in the $L_5$ Trojan state and the remaining 10% were following a classical, non-resonant passing orbit. So very likely and prior to the quasi-satellite phase, the object was already co-orbital with Venus and about 7,500 yr ago it became a quasi-satellite after a close encounter with the Earth.

Regarding its NEO status, our calculations indicate that an actual collision with the Earth during the next 10,000 yr is highly unlikely but a relatively close approach at 0.03782 AU on November 4, 2018, 12:41 UT will take place (the MPC[^10] quotes 0.03764 AU on November 4.90, 2018). Encounters that close to the Earth occur regularly and they
