Asteroid near Earth detected hours after it passed the planet
Washington DC (UPI) Oct 8, 2025 International space agencies say an asteroid zipped by Earth closer than a large number of satellites currently in orbit, but was not detected until hours later. The European Space Agency said Monday that a 3- to 10-foot-wide asteroid was picked up by radar last Wednesday some 265 miles above Earth over Antarctica, near Earth's most southern point, at an altitude similar to that of the International Space Station. "Tracking down a meter-scale object in the vast darkness of space at a tim ... read more |

Asteroid family link strengthened by SwRI analysis of Bennu and Ryugu
Los Angeles CA (SPX) Aug 22, 2025 A Southwest Research Institute study of near-Earth asteroids Bennu and Ryugu provides compelling evidence that both objects originated from the Polana collisional family in the main asteroid belt between Mars and Jupiter. The team compared Polana spectroscopy data with spacecraft and laboratory results from Ryugu and Bennu, revealing strong similarities in their near-infrared spectra that support a shared parent body. "Very early in the formation of the solar system, we believe large asteroi ... read more 
Two different types of asteroids may actually share same origin storyLos Angeles CA (SPX) Aug 22, 2025 Approximately 4.6 billion years ago our solar system formed from a huge disk of gas and dust orbiting our Sun.
