The tiny and cratered Earth does not have any moons and zips throughout the Sunshine a lot quicker than every other World within the solar procedure, therefore why the Romans named it just after their swift-footed messenger god.

In that case, it will make the rocky World a member of an exceptionally pick out club with samples offered on the planet; only the moon, Mars and the large asteroid Vesta have confirmed rocks in human laboratories.
