Mercury has a weak tenuous atmosphere of oxygen, helium, hydrogen, sodium, potassium, and calcium (oxygen makes up most of it sodium and potassium comes from minerals in the rock helium and hydrogen come from the solar wind). While Venus has an atmosphere 90 times denser than the Earth comprised of 95% carbon dioxide, with 100% coverage of clouds made of sulfuric acid.
error
Venus' atmosphere consists mostly of carbon dioxide, with clouds containing of sulfuric acid. There are also compounds of chlorine and fluoride.
By volume, they are oxygen and sodium.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
it makes it very hot and oncreases the amount of radiation
Mercury has virtually no atmosphere due to its proximity to the Sun and its relatively low gravitational attraction force
mercurys period number is 80
Toledo Mercurys was created in 1947.
Toledo Mercurys ended in 1962.
Molecular oxygen, sodium, hydrogen, helium, potassium, argon, nitrogen, carbon dioxide, water vapor, xenon, krypton, & neon
mercurys surface material is made out of nothing but craters
Mercury has a surface pressure that is near enough zero (or a vacuum), the planet holds no real atmosphere due to its small size. There are some trace gases at the surface, but not what one would call a proper atmosphere.
