Recently, as part of space observation, we managed to stumble upon an asteroid 2 km in diameter, dubbed 2020 AV2. It revolved around the Sun, to which it was even closer than Venus. This is strange for the reason that previously created models excluded the possibility of the presence of steroids of this scale in this area. Science knows about 1 million such celestial bodies, but the overwhelming majority of them are significantly removed from the star. Only a small percentage of asteroids with their own orbits are located inside the earth. In the case of Venus, there should be even fewer, we are talking about the Vatiras group, whose representatives have not yet been found. Their size, according to experts, should not exceed a kilometer. Compositionally, 2020 AV2 is close to celestial bodies from the inner region of the Main Asteroid Belt, which is located between Mars and Jupiter. It is unclear what could have caused the asteroid to travel such a path, as well as how it coped with the powerful pull of Venus.

One hypothesis suggests that the asteroid may have formed in space inside the orbit of Mercury, which is even closer to the Sun. Some scientists admit the presence of stability regions there, where during the existence of the solar system large asteroids could have formed and survived. From there, they are closer to the actual orbit, and the motion could be facilitated by the gravity of Venus.
