This observation provides insights into the comet's composition and the distant planetary system from which it originated.

Scientists Discover Meteorites from a Lost Protoplanet Falling to Earth

Scientists Discover Meteorites from a Lost Protoplanet Falling to Earth

A recent study published in Earth and Planetary Science Letters reveals that meteorites known as angrites are remnants of a protoplanet that was destroyed in the early solar system. These meteorites, characterized by their unique volcanic compositions, suggest they originated from a large ancient object with differentiated layers, including a metallic core and a magma ocean. The research, led by Aaron Bell from the University of Colorado, Boulder, provides the first unequivocal evidence supporting the hypothesis that these angrites are samples from a protoplanet that was catastrophically disrupted. This protoplanet, referred to as the angrite parent body (APB), may have been as large as Earth's moon, indicating that significant planetary bodies existed in the early solar system.
