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."

Tiny Asteroid Becomes Earth's Constant Companion
Our Earth has got a small companion. NASA scientists have discovered a tiny asteroid in an orbit around the Sun that keeps it as a constant companion of Earth and will remain so for centuries to come.
