Mercury
Mercury, the planet is a solid rocky body. Mercury, the element is a metal, liquid at room temperature.
The gases surrounding the Earth or any astronomical body is called the atmosphere.
Human beings have only ever landed on one planet - the Earth. Humans have walked on the surface of the moon, but the moon is not considered a planet. We have also sent un-manned probes onto the surfaces of mercury, venus and mars, and we have sent orbital space craft to the other planets of our solar system.
According to the International Astronomical Union, a planet is an astronomical body orbiting a star or stellar remnant thatis massive enough to be rounded by its own gravity,is not massive enough to cause thermonuclear fusion, andhas cleared its neighbouring region of planetesimals.Mercury meets all three requirements and so, by definition, it is a planet.
Pluto.

Mercury got its name from the Roman messenger, Mercury.

The way gravity works, the closer an orbiting body is to the central body,the faster it moves in its orbit. So the planet with the greatest orbital speedwould be Mercury.
