It is made of metals and the core is iron.
mostly rock and iron!!!!The surface of Mercury is most similar to the surface of the moon. Both are about the same age (very roughly) and both are covered with impact craters.
Mercury appears to have a rocky surface like the Moon, with similar craters but with additional changes made by the extraordinary temperature ranges that the surface experiences.
The question is inappropriate because the surface of Mercury is not unmapped!
Mercury has a rocky surface, it is the closest planet to the sun in the solar system (however not the hottest). There are only 4 gas giants in our solar system, (Jupiter, Saturn, Neptune and Uranus) how ever astronomers have discovered many other gas planets orbiting other stars in the galaxy. Hope this helps you:)
Meteorites smash into Mercury's surface to be so rocky
rockyMercury surface is made of hydrogen , and helium .
nothing
the surface of mercury is made up of rocks
I'm only 8 so the surface of mercury is rocks I'm guessing
No. Mercury has a surface made of rock and a large metallic core. It has virtually no atmosphere.
It is made of metals and the core is iron.
its made from iron okay
rockymercury surface is made of hydrogen , and helium .
the core is made up of gas,and the surface is rock,craters and dust
no nothing man made have made it to the surface
Mercury is made up primarily of rock,helium,hydrogen,dust,dirt, and ice.
