In a rare "time-critical" decision, the James Webb Space Telescope will study the true size of the "potentially hazardous" asteroid 2024 YR4 twice over the next few months. The asteroid has a roughly 2.3% chance of impacting Earth in 2032.
Probably not every 4 years. After 2032, Earth will not be near the intersection point of the two orbits for a while. It might be decades before it’s even close.
Even if it misses, it has a chance to come back every 4 years
