(Phys.org)—The asteroid Vesta, which exists between Mars and Jupiter, is one of the largest in the solar system—it is also considered to be a protoplanet because it has a core, mantel and crust. Now, a research team made ...
Seeking to better understand the structure and composition of asteroid 4 Vesta, one of the major protoplanets of the asteroid belt, a team of researchers has developed a new model that reproduces the global topography observed ...
