New research shatters long-held beliefs about asteroid Vesta
78% Informative
For decades , scientists believed Vesta , one of the largest objects in our solar system's asteroid belt, wasn't just an asteroid.
They concluded that Vesta has a crust, mantle and core -- fundamental properties of a planet.
Vesta 's surface is covered in volcanic basaltic rocks indicated Vesta went through a melting process called planetary differentiation.
Jacobson 's lab was already exploring the consequences of giant impacts during the planet formation era.
He's working with one of his graduate students on the idea that some asteroids in the asteroid belt are pieces ejected from the growing planets.
This paper is only the beginning of a new direction of study, Jacobson said.
