Abstract

Liquid assets Our Solar System formed about 4.6 billion years ago, and within 4 million years small planetary bodies had formed, some melting to form volcanic and related rocks. Two families of meteorites (the HEDs and angrites) are thought to have originated from asteroids that melted at this time. New oxygen isotope measurements confirm that these meteorites are from two distinct asteroids that underwent large-scale melting in the early Solar System. These new results show that early, global-scale melting was a feature of all the differentiated planets (Earth, Moon and Mars) and asteroids so far sampled.
