Asteroid 2024 YR4: Scientists Eagerly Await Potential Moon Collision—Could It Be a Game Changer?

A recent asteroid, 2024 YR4, has caused a stir among scientists. Initially thought to be a threat to Earth, it now seems more likely to strike the Moon instead. New findings estimate there’s about a 2% chance it could hit the lunar surface.

Thanks to the James Webb Space Telescope, we now have clearer data on the asteroid’s path. Julia de León, a planetary scientist and part of Europe’s planetary defense team, expressed her enthusiasm. “If it hits the Moon, it wouldn’t harm us. But it would give us a rare chance to observe a lunar impact,” she said. She noted that while craters cover the Moon, most impacts we’ve seen were small; we’ve never witnessed one larger than about 164 feet across.

Asteroid 2024 YR4 first made headlines back in February when it was classified as a potential risk. An initial assessment by NASA and the European Space Agency suggested a 3.1% chance of it hitting Earth. This raised alarm, prompting the United Nations to activate its Planetary Security Protocol for the first time ever. However, as observations improved, scientists quickly determined the risk to our planet was nearly nonexistent.

Yet, the Moon could face some danger. The asteroid is about 60 meters long, significant enough to catch experts’ attention. De León noted that a collision could cause destruction over a wide area. “An impact could affect a region of 50 to 62 miles across,” she cautioned.

Historically, we know asteroids can cause damage. In 2013, a smaller asteroid exploded over Chelyabinsk, Russia. That rock was just 20 meters but released energy equal to 35 Hiroshima bombs, injuring around 1,500 people and damaging thousands of buildings. The Chelyabinsk event serves as a reminder of the potential risks posed by space rocks.

While Earth is off the hook, the scientific community is keen to see what happens if 2024 YR4 does collide with the Moon. De León hopes it will. “We could closely track the impact,” she said. “It would be a fantastic learning opportunity.”

Researchers will continue to monitor the asteroid, with further observations planned for May to refine predictions on its lunar impact. The excitement surrounding this asteroid underscores the ongoing need for vigilance and study in planetary defense. Our understanding of such cosmic objects not only enhances our safety but also deepens our knowledge of the universe.
