MERCURY RISING
Collision of equal sized bodies may explain Mercurys unique composition



Sao Paulo, Brazil (SPX) Sep 25, 2025
A new study suggests that Mercury's unusual structure may have resulted from a grazing collision between two similar sized protoplanets, rather than a rare catastrophic impact with a much larger body. Mercury's dense metallic core makes up about 70% of its mass, while its rocky mantle remains unusually thin compared to other terrestrial planets. The research, led by Patrick Franco of the National Observatory in Brazil and postdoctoral researcher at the Institut de Physique du Globe de Paris, used ... read more
