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,

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

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,

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.

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.

The little space rock, called 2025 TF, safely passed within roughly 250 miles (400 km) of our planet on Tuesday (Sept. 30) at 8:49 p.m. EDT (Wednesday, Oct. 1 at 0049 GMT), according to NASA data. That flyby puts the asteroid at the same approximate altitude as the International Space Station.
