A car sized asteroid can sound like a cliffhanger, yet the real tension lives in the math. NASA’s trackers list 2026 CR2 for a close pass on Feb. 17, 2026, moving about 12,616 miles per hour, with an ...

NASA officials warn thousands of undetected “city killer” asteroids may be circling near Earth. With limited deflection tools ready, are we prepared if one suddenly shifts onto a collision course?

Asteroid 2024 DW flew about 139,000 miles (224,000 km) away from Earth. The space rock was estimated to be about 43 feet wide (13 m). Credit: Space.com | animation: NASA/JPL-Caltech | edited by Steve ...

NASA planetary defense experts warn that up to 15,000 undetected asteroids could devastate a major city on Earth.

NASA experts warned that human beings are vulnerable to thousands of hidden “city-killer” asteroids. A new space telescope may improve detection, but we currently lack tools to stop a threat., US Buzz ...

NASA's James Webb Space Telescope is tracking asteroid 2024 YR4, which has a small chance of hitting the Moon in 2032, to refine its trajectory and improve prediction models.

NASA planetary defense experts report that mid-size near-Earth asteroids could cause regional damage, with detection and deflection remaining limited, according to New York Post and AAAS reports.

James Webb Space Telescope (JWST) will provide insights far more precisely than ground telescopes can manage now, as the rock is too far away for most Earth-based instruments.

Kelly Fast, a planetary defense officer at NASA, says there could be 15,000 undetected asteroids that have the potential to take out a city.

Two NASA scientists claim Earth is at risk from over 25,000 unknown asteroids that are yet to be discovered. If one of them moves towards the planet, no amount of preparation or a mission like DART ...

NASA officials warn that around 15,000 'city-killer' asteroids remain undiscovered, many lurking in a stubborn observational blind spot near the sun.

NASA has since downgraded that possibility to zero percent, but the asteroid continues to be tracked by NASA's James Webb Space Telescope this week as there's a 4 percent chance it could collide with ...
