What Is The Surface Of Mercury Made Of

Mercury s core is thought to be made of molten nickel iron with a mantle of solid rock and a surface of loose rocks and dust.

Surface features of mercury. The eight planets revolving around the sun are all very unique yet still connected at a certain level. Information about mercury s composition is based on data from the spacecraft mariner 10 launched in 1973 and the probe messenger the mission for which ran from 2011 to 2015. The core takes up nearly 3 4 of the planet s diameter.

Like the other three terrestrial planet mercury contains a core surrounded by a mantle and a crust. But mercury s core makes up a larger portion of the planet than others in the solar system. Mercury s iron core is about the size of the moon. The surface of mercury is marred by an impressive number of craters.

Become a member and. In the case of. Mercury s surface is primarily made of heavier elements including iron because the lighter elements have been pushed away farther by the sun which. Mercury s surface is similar in appearance to that of the moon showing extensive mare like plains and heavy cratering indicating that it has been geologically inactive for billions of years because knowledge of mercury s geology had been based only on the 1975 mariner 10 flyby and terrestrial observations it is the least understood of the terrestrial planets.

Messenger used x ray fluorescence spectra to study the surface composition of mercury. The messenger spacecraft revealed that mercury has some unique landforms more smooth plains and surface compositions low in iron and high in sulfur that are unlike any measured on the moon. Scientists believe that mercury has an interior composition similar to earth. Mercury is made up of iron and silica rocks.

It found a high ratio of magnesium to silicon and low ratios of aluminum and calcium to silicon which showed that the crust was not rich in feldspar like that of the moon. See full answer below. The surface of mercury at first glance looks very much like that of the moon but in fact it is different in several ways. A thicker atmosphere would have.

Our solar system is full of mysteries. The cratering is deeper than on most terrestrial planets because of its lack of an atmosphere. The planet has more iron in its core than any other entity in our solar system.
