Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
Mercury is a chemical element; it has symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm) from the Greek words hydor ' water ' and argyros ' silver ', from which its chemical symbol is derived. [8]

Mercury is one of four inner planets in the Solar System. It is a terrestrial planet like Earth. It is the smallest planet in the Solar System. It has a radius of 2,439.7 km (1,516.0 mi). [2] Mercury is even smaller than some of the largest moons in the solar system, such as Ganymede, the largest moon of Jupiter and Titan, the largest moon of ...
Mercury is the smallest planet in our solar system and the nearest to the Sun. Mercury is only slightly larger than Earth's Moon. Its surface is covered in tens of thousands of impact craters.
Mercury, being the closest to the Sun, with a weak magnetic field and the smallest mass of the recognized terrestrial planets, has a very tenuous and highly variable atmosphere (surface-bound exosphere) containing hydrogen, helium, oxygen, sodium, calcium, potassium and water vapor, with a combined pressure level of about 10 −14 bar (1 nPa).
