- A newly identified asteroid, 2024 YR4, poses a 2.2% chance of impacting Earth on 22 December 2032.
- Measuring between 40 and 90 metres, its potential impact could cause significant damage within a 50-kilometre radius.
- The asteroid’s speed is estimated at approximately 61,200 kilometres per hour upon entry.
- Asteroids of this size have historically struck Earth every few thousand years, causing substantial destruction.
- The Tunguska event of 1908 and the Chelyabinsk incident of 2013 serve as historical examples of such impacts.
- Ongoing observations are crucial in refining the asteroid’s risk assessment and understanding its trajectory.
A newly discovered asteroid, named 2024 YR4, has astronomers on high alert. With a 2.2% chance of colliding with Earth on 22 December 2032, the European Space Agency has increased its risk assessment from a prior 1.2%, fueling curiosity and concern globally.
Measuring 40 to 90 metres wide, 2024 YR4 is comparable to a large building. Dr. Paul Chodas, a prominent manager at NASA’s Jet Propulsion Laboratory, highlighted that if this space rock were to hit, its rapid entry at approximately 61,200 kilometres per hour could induce devastating damage within a 50-kilometre radius. However, many factors still play into its trajectory, and ongoing observations are key to fine-tuning its risk profile.
Historically, asteroids of similar size have struck the Earth every few thousand years, often leaving significant devastation in their wake. The infamous Tunguska event in 1908 levelled 2,150 square kilometres of Siberian forest after a smaller asteroid exploded mid-air. Meanwhile, the Chelyabinsk event in 2013 led to substantial injuries and damaged buildings due to a rogue meteor bursting over Russia.
The Asteroid Terrestrial-impact Last Alert System first spotted 2024 YR4 on 27 December, igniting alerts within NASA’s monitoring systems as it quickly ascended to the top of their radar.
In essence, while the discovery of 2024 YR4 raises eyebrows, it’s a reminder of our universe’s unpredictability. As astronomers gather more data, the likelihood of impact may diminish, turning what seems like a cosmic threat into just a cautionary tale in the skies. Stay tuned—our planet’s defenders are on the case!
