Solar System's First Planets May Have Formed From Fire, Not Ice

Original: The Solar System’s First Planets Were Made of Fire, Not Ice

A new report from Universe Today claims the Solar System's earliest planets formed in fiery, hot conditions near the young Sun rather than in the cold outer regions long assumed. The idea challenges the standard picture of planet formation, in which rocky worlds built up close to the Sun while icy bodies accumulated farther out. Astronomers and space enthusiasts are weighing what this would mean for theories of how Earth and its neighbours came together.

Why now: It challenges the long-standing standard model of how planets formed in the early Solar System.
