Astronomers trace the origin of meteorites that have struck Earth
Meteorites - rocks that fall to Earth from space - have pelted our planet from its birth about 4.5 billion years ago to today, often causing scant damage but sometimes triggering cataclysms. But from where exactly are these space rocks coming?
We Finally Know Where Most Meteorites on Earth Actually Came From
"Supporting evidence includes the existence of associated dust bands, the cosmic-ray exposure ages of H chondrite meteorites, and the distribution of the pre-atmospheric orbits of meteorites," write the authors in one published paper.
Scientists Discover Surprising Origin of Most Meteorites that Strike Earth
Until now, only 6% of meteorites had a known source, but now we can trace the origin of more than 70% of these rocks.
The origin of most meteorites finally revealed
An international team has successfully demonstrated that 70% of all known meteorite falls originate from just three young asteroid families. These families were produced by three recent collisions that occurred in the main asteroid belt 5.
Groundbreaking Discovery Uncovers Origins of Most Meteorites
An international research team has revealed the origin of most meteorites, announced the French National Center for Scientific Research (CNRS), which co-led this discovery on the French side. The team,
70 Percent Of Meteorites That Hit Earth Appear To Have A Common Origin
Three new studies have revealed the common origin of most of the meteorites that hit Earth, linking them to collisions in the relatively recent past. Though the Earth doesn't make a fuss about it, every day it is bombarded with around 44,
Scientists Uncover Surprising Origin of Most Meteorites Hitting Earth
A new breakthrough in the study of meteorites has revealed that over 70% of meteorites that strike Earth come from just three asteroid families. This discovery, outlined in recent research published in Nature and Astronomy and Astrophysics,
