A newly discovered asteroid, designated 2024 YR4, has drawn significant attention from the global scientific community after calculations revealed a 1.3% chance of it colliding with Earth on December 22, 2032. Measuring approximately 100 meters in width, the asteroid was first observed on December 27, 2024, by an automated telescope in Chile. Since then, it has risen to the top of impact risk lists maintained by NASA and the European Space Agency, marking the first time Earth’s planetary defense systems have been triggered in response to a newly discovered near-Earth object.

Despite the initial alarm, experts stress that the odds remain heavily in favor of the asteroid passing by harmlessly. Colin Snodgrass, a professor of planetary astronomy at the University of Edinburgh, has emphasized that while the asteroid merits further observation, it is unlikely to pose a serious threat. However, given its size, an impact—though not an extinction-level event—could still cause widespread devastation on a local scale, comparable to the 1908 Tunguska explosion that flattened thousands of square kilometers of Siberian forest.

The asteroid has been classified as a Level 3 event on the Torino Impact Hazard Scale, a rare designation that signifies an object with a one percent or greater chance of impact in the next decade. The only other asteroid ever to receive a higher rating was Apophis, which in 2004 briefly reached Level 4 before further observations ruled out any possibility of impact within the next century. The current uncertainty surrounding 2024 YR4’s orbit has prompted a coordinated global response from two major planetary defense organizations. The International Asteroid Warning Network has launched an effort to gather additional data to refine its trajectory, while the Space Mission Planning Advisory Group is considering potential intervention strategies should they become necessary.

One of the possible mitigation strategies involves deflecting the asteroid using an intercepting spacecraft, a technique successfully tested in NASA’s 2022 DART mission. The mission demonstrated that kinetic impact technology could alter an asteroid’s trajectory, proving that such an approach could work on an object like 2024 YR4 if future calculations indicate a continued risk of collision. However, for now, the primary focus remains on observation.

Astronomers will continue tracking the asteroid in the coming months, but as it moves away from Earth, precise measurements will become increasingly difficult. The next major observation window is expected in 2028, which will provide scientists with a clearer picture of its path and any potential danger it might pose. Until then, researchers remain cautiously optimistic, reiterating that the more data they gather, the more accurate their predictions will become.

Fortunately, Earth’s planetary defense squad is on the job, scanning the skies and ready to handle whatever space throws our way. Thanks to ongoing asteroid tracking, we’re not just waiting for a rock to drop—we’re staying one step ahead, with science, strategy, and maybe even a well-placed space nudge if needed.

Super glue: it’s tiny, it’s sticky, and it’s way more powerful than you think! In this video from Veritasium, host Derek Muller takes you on a fun journey through this accidental wonder of science. Originally invented in the 1940s as a clear plastic for gunsights, it wasn’t long before its incredible sticking power was discovered—and yes, it works on skin too! How? Well, when it meets water, it forms strong polymer chains that bond almost anything—except certain plastics (sorry, plastic toys). You’ll learn why this stuff can hold thousands of pounds, why it’s used in emergency rooms, and how to get it off your fingers without drama. It’s not just about sticking things together—could super glue actually help solve plastic waste? Watch below!
