Interior of Mercury Posters
by solarviewsThis diagram shows what scientists believe to be the interior structure of Mercury.
Most of what is known about the internal structure of Mercury comes from
data acquired by the Mariner 10 spacecraft that flew past the planet
in 1973 and 1974. Mercury is about a third of the size of Earth, yet
its density is comparable to that of Earth. This indicates that Mercury
has a large core roughly the size of Earth's moon or about 75% of
the planet's radius. The core is likely composed of 60 to 70% iron
by mass.
Mariner 10's measurements of the planet reveals a dipolar magnetic field
possibly produced by a partially molten core.
A solid rocky mantle surrounds the core with a thin crust of about 100
kilometers.

mercury's interior
it's good, but is the core molten or cool? what is the mantle made of?
