Summary

Story summary

Many Venus near-coorbital asteroids may remain undetected by Earth telescopes.
Only 20 Venus co-orbital asteroids are known; simulations suggest many more exist, 300-390 meters.
Impact energy could reach 150-410 megatons, enough to destroy large cities.
Ground-based telescopes struggle to detect them near the Sun; space missions like NASA's Near-Earth Object Surveyor (NEO Surveyor) and China's CROWN are essential.
