Detailed explanation-1: -Atmosphere. Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids. Mercury’s exosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium.
Detailed explanation-2: -The closest planet to the Sun is Mercury. That’s why it’s sometimes called the “innermost planet.”. It orbits the Sun at an average distance of 36 million miles (58 million kilometers). There are no other planets that are closer to the Sun than Mercury.
Detailed explanation-3: -Atmosphere and Weather: Mercury has an extremely thin and non-protective atmosphere. For all practical purposes, the atmosphere is nearly a vacuum. The sparse atmosphere is primarily composed of oxygen, sodium and hydrogen. Mercury’s atmospheric atoms are continuously being lost to space.
Detailed explanation-4: -If there is no air or atmosphere then there will still be gravity. An example of this would be the moon and Mars.
