Mars is still an "embryo" of planet


The planet Mars twisted in record time and reached its current size in just three million years, much faster than scientists thought. That rate of formation of the Red Planet could explain that its mass is one tenth of that of the Earth. The study supports a theory more than two decades, according to which the planet remained small because it avoided collisions with what would become the "planetary construction materials", ie other objects in space. The finding is published in the journal Nature.

In the early days of the solar system before the planets were formed, a cloud of gas and dust surrounding the Sun Scientists believe that the planets arose from the accumulation of this material driven by electrostatic energy.
