A theoretical protoplanet named 'Theia' is thought to have collided with the forming Earth, and part of the material ejected into space by the collision accreted to form the Moon.

The oldest continental crustal rocks on Earth have ages in the range from about 3.7 to 4.28 billion years 45 and have been found in the Narryer Gneiss Terrane in Western Australia, in the Acasta Gneiss in the Northwest Territories on the Canadian Shield, and on other cratonic regions such as those on the Fennoscandian Shield. In contrast, the bulk of the continental crust is much older. Earth has probably always had some form of basaltic crust, but the age of the oldest oceanic crust today is only about 200 million years. Tigre 4000 is the isodiametric Antonio Carraro tractor which most perfectly unites compactness and technology.
