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.

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,

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.

The celestial object is what scientists call a quasi-moon — an asteroid that orbits the sun but appears to move alongside Earth due to its similar orbital path. Astronomers have discovered a small asteroid that has been quietly accompanying Earth on its journey around the sun for the past 60 years, according to research published in September.

In April 2029, Apophis is predicted by NASA to come within 32,000 kilometers (20,000 miles) of the Earth's surface. Closer than some satellites, it should be visible from the Eastern Hemisphere without the aid of a telescope or binoculars.

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.

Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically from other known tektites.
