As September 15, 2024, approaches, space enthusiasts and casual observers alike are curious about the asteroid 2024 ON, which is set to make a “close” approach to Earth. With sensational headlines about potential hazards, it’s important to take a closer look at the facts surrounding this near-Earth object (NEO) and its journey through space.
What is 2024 ON?
2024 ON is a sizable asteroid, measuring about 720 feet (220 meters) in diameter—comparable to a 60-story skyscraper. It was first detected in 2024 by NASA’s Near-Earth Object Observations Program, which is tasked with tracking asteroids and comets that could pose a threat to Earth. Classified as a “potentially hazardous asteroid” due to its size and proximity during this flyby, 2024 ON will come within about 0.62 million miles (1 million kilometers) of our planet, more than twice the distance between Earth and the Moon.
Why the “Potentially Hazardous” Label?
NASA defines any space object larger than 460 feet (140 meters) in diameter that comes within 4.65 million miles (7.5 million kilometers) of Earth as potentially hazardous. This doesn’t mean the asteroid will hit Earth; it simply warrants close observation due to its proximity. In the case of 2024 ON, while the distance may seem close on a cosmic scale, it’s still far enough away to pose no immediate danger to Earth or its inhabitants.
Tracking and Monitoring
NASA’s Center for Near-Earth Object Studies (CNEOS) and other global space agencies continuously track asteroids like 2024 ON. Using radar, telescopes, and complex orbital models, scientists calculate the paths of these objects far into the future to assess any potential risk. The good news is that, according to current data, Earth faces no significant asteroid threat for at least the next 100 years.
How Close is Close?
While 2024 ON’s closest approach will be around 0.62 million miles, this is still a comfortable distance from Earth, with no chance of impact. To put it in perspective, this is more than twice the distance from Earth to the Moon. Though classified as a near-Earth object (NEO), 2024 ON is not considered a real threat.
A Spectacular (But Safe) Sight
For those interested in space events, this close encounter offers a unique stargazing opportunity. The asteroid will be visible in the Northern Hemisphere, and the Virtual Telescope Project will provide live coverage of the event. If you’re a fan of astronomy or just curious about space, this could be an exciting chance to witness an asteroid passing “near” Earth, all while being reassured of your safety.
Conclusion
While the notion of a potentially hazardous asteroid flying past Earth may stir up concerns, 2024 ON is not a cause for alarm. NASA and other space agencies are well-equipped to track and monitor such objects, ensuring that no surprise asteroid impacts are headed our way anytime soon. Instead of worrying, take this opportunity to marvel at the wonders of space from a safe distance!
