COLLEGE PARK, Md. (UPI) — Two meteorites found in Antarctica are from an asteroid with an outer layer or crust similar to the Earth’s continents, U.S. scientists said Thursday.

The finding is the first from an asteroid with an Earthlike crust, the University of Maryland geochemists and other researchers reported in the  Nature Journal.

They said the rocks are more than 4.52 billion years old and were formed during the birth of the solar system.

Their age, combined with the oxygen isotope data, “points to their origin from an asteroid rather than a planet,” Day said.

Asteroids, sometimes called minor planets or planetoids, are bodies, primarily of the inner solar system, that are smaller than planets but larger than meteoroids, but exclude comets.
