Tiny Asteroid 2025 TF Zooms Past Earth Undetected, Closer Than Satellites
A small asteroid named 2025 TF surprised astronomers after flying only 265 miles above Antarctica, lower than many satellites. Detected post-passage by ESA, it underscores the challenge of spotting small, fast-moving space rocks before they come close to Earth.

Astronomers Reveal Sudden Explosion of Small Asteroid Over France
In February 2023, asteroid 2023 CX1 exploded suddenly over France, stunning scientists. Tracked only hours before impact, the tiny rock disintegrated in a powerful airburst, scattering meteorites across Normandy. The rare event provides crucial insights into asteroid behavior and raises new considerations for future planetary defense strategies.

NASA’s OSIRIS-REx Mission Finds Stardust in Asteroid Bennu Older Than the Solar System
NASA’s OSIRIS-REx mission has found presolar stardust grains inside Bennu’s samples. These tiny particles, older than the Sun, carry chemical fingerprints of ancient stars and interstellar space. Bennu thus serves as a pristine time capsule, preserving the earliest clues to the birth of our solar system.

NASA's Mission Not Only Altered Asteroid's Path, But Its Shape Too, Says New Study
According to an analysis of a collision between NASA's DART probe and the asteroid Dimorphos back in September 2022, the tiny asteroid's shape could have changed significantly as a direct result of the impact.

NASA's Lucy Spacecraft Discovers "Mini Moon" Orbiting Asteroid Dinkinesh
With its first flyby of the asteroid Dinkinesh, Lucy discovered it is not one single asteroid, but a system of two, with a small 220m-wide satellite spinning around it.

NASA Aims to Redirect Asteroid in DART Mission's First Attempt at Planetary Defence
NASA's Double Asteroid Redirection Test, or DART, will attempt to alter the orbit of the asteroid Dimorphos, on September 26. The US space agency is set to create history when it crashes a spacecraft into the asteroid, attempting to deflect it from its trajectory. A tiny moon of the asteroid Didymos, the asteroid Dimorphos is an ideal target for NA...

Asteroids Appear Rough Due to Space Dust Hopping on Them, Suggests Research
A new study from physicists suggests that tiny grains of space dust may hop around on the surface of asteroids, making them appear rough. The study, published in the journal Nature Astronomy, may help scientists understand how asteroids bring them dangerously close to Earth.

Space Rovers Become First-Ever Spacecraft To Land On Asteroid Surface
On a primitive piece of space rock more than 100 million miles from Earth, two tiny robotic explorers took their first cautious "hops" this weekend - the first movements made by any human-made spacecraft across the surface of an asteroid.

Meet Earth's 'Quasi-Satellite' - A Tiny Asteroid That's Followed Us For A Century
Earth has only one true natural satellite: the moon. But now scientists have found a fellow satellite of the sun that's been our constant companion for more than 100 years. Because of the way the space rock wobbles in orbit, it actually circles our own planet in addition to circling the sun.

Earth Has a Constant Companion in the Form of a Tiny Asteroid: Study
"Since '2016 HO3' loops around our planet but never ventures very far away as we both go around the Sun, we refer to it as a quasi-satellite of Earth."
