Meet 2025 SC79: Skyscraper-size asteroid hidden in sun’s glare discovered zooming at record speed

Astronomers have identified a skyscraper-sized asteroid, 2025 SC79, orbiting incredibly close to the Sun and at a near-record speed. This ‘twilight asteroid,’ detected using the Dark Energy Camera, poses a significant threat due to its proximity and speed, making it harder to track and potentially more dangerous than previously known ‘city-killer’ objects.
