Vatira-class near-Earth objects (NEOs) have orbits entirely interior to theorbit of Venus with aphelia $0.307<Q<0.718$ AU. Recently discovered asteroid2020 AV$_2$ by the Zwicky Transient Facility on 4 January 2020 is the firstknown object on a Vatira orbit. Numerical integrations of 2020 AV$_2$'s nominalorbit show it remaining in the Vatira region for the next few hundred kyrbefore coupling to Venus and evolving onto an Atira orbit (NEOs entirelyinterior to Earth's orbit with $0.718<Q<0.983$ AU) and eventually scatteringout to Earth-crossing. The numerical integrations of 9900 clones within 2020AV$_2$'s orbital uncertainty region show examples of Vatira orbits trapped inthe 3:2 mean-motion resonance with Venus at semimajor axis $a\approx0.552$ AUthat can survive on the order of a few Myr. Possible 2020 AV$_2$ orbits alsoinclude those on Vatira orbits between Mercury and Venus that only rarely crossthat of a planet. Together the 3:2 resonance and these rarely-planet-crossingorbits provide a meta-stable region of phase space that are stable ontimescales of several Myr. If 2020 AV$_2$ is currently in this meta-stableregion (or was in the past), that may explain its discovery as the first Vatiraand may be where more are discovered.
