In the distant past, the solar system was rife with impacts and collisions. Millions of rocky objects zoomed chaotically through the system, smashing into each other in collisional cascades. Over time,

The newly discovered "twilight" asteroid, 2025 SC79, was obscured by the sun's glare until an astronomer pointed the Dark Energy Camera at it, highlighting the potential dangers of unseen asteroids.

A plan by a team of scientists suggests using nuclear explosive devices to prevent an asteroid, 2024 YR4, from striking the moon in 2032.

Asteroid 2024 YR4 has a 4% chance of colliding with Earth’s moon in 2032, and some scientists are considering whether they should nuke it. The study was recently submitted by over a dozen scientists to arXiv,

A small asteroid, known as 2025 TF, flew over Antarctica on October 1, 2025, at an altitude of only 266 miles.

There are many programs that detect near-Earth asteroids as part of countries' planetary defense strategies. In the case of asteroid 2025 TF, it was the Catalina Sky Survey, based in Arizona and operated by the University of Arizona, that first detected the asteroid hours after it passed Earth.

A paper from several NASA scientists and other researchers explores whether an asteroid with a 4% chance of hitting the moon in 2032 should be deflected or blown up.

After overcoming significant obstacles, NASA’s $20 Million Mission to the “God of Chaos” Asteroid is ready for launch. This mission, which targets a potentially hazardous near-Earth object known for its erratic orbit,
