Asteroid 2024 YR4, spotted late last year, is being closely tracked by scientists. It is estimated to be between 40 and 90 meters in size, with a potential collision date of December 22, 2032. While the risk was initially calculated at 1.3%, it has now risen to 2%. However, experts urge not to panic, as the probability of impact is still low. Currently, there is a 98% chance it will not hit Earth.
Astronomers are still gathering information about its orbit. Initially, the asteroid's trajectory was uncertain, but as more data is collected, the risk increases. As the "area of uncertainty" shrinks, the Earth may eventually be outside this zone, reducing the impact risk to zero.
Time is crucial as the asteroid is moving away from Earth and won't be visible again until 2028. Astronomers are utilizing the James Webb Space Telescope to better understand the asteroid's size and orbit. If necessary, this information will help develop a plan of action.
While we are not yet at a deflection stage, NASA has successfully tested asteroid deflection by crashing a spacecraft into a small asteroid. Monitoring will continue to ensure preparedness for any potential impact.
