This is why, in May of 2024, the James Webb telescope was used to focus on a tiny point in movement. This observation changed the probabilities of a future collision and the object was the 2024 YR4 asteroid: a spatial rock of between 53 and 67 meters of diameter, kind of like the size of a 10-floor building.

When this asteroid was found at the end of 2024, it became popular (for a short time) because it had the highest probability ever registered to impact Earth among large asteroids. According to what scientists first calculated, there was a 3.1% chance of hitting Earth in 2032. This percentage might seem small, but in terms of planetary defense was enough for NASA to start simulations and studies to understand how to respond if such an event ever became real.
