The comparative analysis between the Chelyabinsk meteor and the newly identified asteroid with a 3.1% probability of impacting Earth is particularly important for understanding potential risk scenarios. The 2013 Chelyabinsk meteor was a wake-up call, highlighting how even relatively small celestial objects can cause considerable local damage. Measuring approximately 66 feet wide, the Chelyabinsk meteor released energy equivalent to 500 kilotons of TNT when it exploded in the atmosphere, which led to over 1,500 people being injured by glass from shattered windows and other indirect effects. By contrast, the current asteroid threat reportedly ranges from 130 to 300 feet wide, potentially making its atmospheric entry more impactful [1](https://www.kltv.com/2025/02/21/nasa-projects-highest-probability-ever-asteroid-hit-2032/).

One key similarity between the Chelyabinsk event and this projected impact is the atmospheric entry phenomenon known as an airburst. In both cases, airbursts occur when meteors or asteroids disintegrate high in the Earth's atmosphere, producing massive pressure waves. These waves are primarily responsible for the damage, leading experts to anticipate similar consequences if the new asteroid were to explode over an uninhabited area like the Pacific Ocean. Such an event would involve significant shockwaves capable of damaging structures within a 30-mile radius, although the potential for human harm would be vastly reduced compared to a populated area impact [1](https://www.kltv.com/2025/02/21/nasa-projects-highest-probability-ever-asteroid-hit-2032/).

Global monitoring and preparation measures have significantly evolved since 2013, reducing the panic and enabling more informed public and governmental responses to potential threats. Today, coordinated international efforts, including space missions like NASA's DART program, aim to mitigate these risks by developing asteroid deflection techniques [3](https://science.nasa.gov/planetary-defense/). This proactive stance offers more confidence in handling potential asteroid impacts compared to past experiences such as Chelyabinsk, where the response was largely reactionary.
