Mercury, the smallest planet in the Solar system, is classified as a terrestrial planet along with Earth, Venus, and Mars. The surfaces of these terrestrial planets are composed of silicate rocks and these planets are classified in a group called inner planets. Mercury and other inner terrestrial planets are made up of a metallic core

Mercury is the planet closest to the sun and is the smallest planet in the solar system. It is so small that some natural satellites exceed its size like Jupiter’s Ganymede and Saturn’s Titan. However, Mercury possesses more mass than both Ganymede and Titan. Despite its size, it is only second to Earth in density

Mars, is considered as the Earth’s closest neighbor, holds quite a few similarities to Earth. These include having volcanoes such as the biggest Olympus Mons, valleys such as the Valles Marineris which stretches 2/3 across the planet (or from New York to LA on Earth) and even deserts.

Mercury is the innermost planet in the Solar System, but surprisingly it is not the hottest planet; that would be Venus. The reason for this is that Mercury has a thin atmosphere that cannot trap solar heat. Its maximum atmospheric pressure is estimated to be 0.00000000003 pounds per square inch; on Earth, the atmospheric pressure
