A planetary scientist has used careful mathematical calculations to determine the density of Mercury's crust, which is thinner than anyone thought. Mercury is small, fast and close to the sun, making ...

Mercury’s high density and large iron content could have been caused by magnetically excited collisions within part of the Sun’s protoplanetary disc, suggests new research from scientists at the ...

The second NASA mission to Mercury was the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (or MESSENGER) space probe. The purpose of this mission was to clear up six key issues relating ...

Mercury still has a molten core, like Earth does. As Mercury's core slowly cools, the density of that core increases and it gets slightly smaller. NASA/Johns Hopkins' Applied Physics Laboratory Humans ...
