The internal structure of Mercury
Mercury is larger than Earth's moon a little. No atmosphere enveloped Arid and full With many craters Most of the holes that age. I have shown that over the past volcanic activity, otherwise these holes must be covered with ash and lava. Mercury's core is a large iron core with a diameter of 3,700 kilometers (about 42% by volume of the entire planet) around a core mantle (thickness about 600 km), and a hard shell cover. Which are composed of silicate sand, like that found on Earth.
