On September 15, 2024, asteroid 2024 ON made a close approach to Earth, passing within 1 million kilometers of the planet. While this may seem far, it’s considered close in astronomical terms, offering a rare opportunity for scientific study. Measuring around 720 feet in diameter, 2024 ON is part of a class of asteroids known as near-Earth objects (NEOs), which NASA continuously monitors.
Although there was no risk of impact, this event allowed scientists to gather critical data on the asteroid's composition and trajectory, refining our understanding of such celestial bodies and improving models for planetary defense. Public interest was also piqued, with the Virtual Telescope Project providing a live stream of the event, making it accessible to astronomy enthusiasts globally.
This close flyby underscores the importance of ongoing efforts by agencies like NASA and ESA to track and assess the risk of potential future asteroid threats..
