All of that swirling orange and yellow and white IS the atmosphere. Astronomers think that inside that atmosphere as a dense, solid core that has such a massive gravity that it holds in that 30 mile thick atmosphere.
There is no atmosphere in Mercury due to the the combination of two factors:
1) Due to the high average temperature on Mercury makes individual molecules of the atmosphere move very fast.
2) The low gravity (to be more precise: escape velocity) makes it easy for molecules in the atmosphere to escape. In summary, if any atmosphere develops on the planet (for example, something leaking out of the ground), it won't last long.
"Meteor" is, technically speaking, a body burning up in Earth's atmosphere. It's kind of silly to talk about it having its own atmosphere at that point; it is, however, surrounded by hot gasses, part of which is Earth's atmosphere and part of which is vaporized meteor.
Mercury's gravity is too weak to hold on the an atmosphere for any length of time. Instead it has an exosphere containing hydrogen, helium, oxygen, sodium, calcium, potassium. The composition is not stable as atoms are continually being lost, and replenished in a variety of ways.
mercury has almost no atmosphere only a thin layer of helium and sodium gas.
Mercury has a very thin exosphere made up of atoms that come from solar radiation. it contains helium, hydrogen, sodium, calcium, and oxygen.
The atmosphere of Mercury consists of helium, oxygen, hydrogen and very small amounts of magnesium, calcium, potassium and sodium. The atmosphere of Mercury has virtually no gravity.
yes it's called hydrogen and helium.
carbon dioxide
Mercury has the thinnest atmosphere of all the planets in our solar system. Mercury's atmosphere is primarily made up of oxygen, sodium, and hydrogen.
Mercury does not have rings and it has no atmosphere.
Mercury has no Atmosphere, unlike Earth, which has an Atmosphere made out of Air. Mercury is dry because their is no water on Mercury.
it is made of heat resistant rock and magma. there is no atmosphere.
Its low mass has made it hard for it to retain any gases at all as an atmosphere
Mercury's atmosphere is mainly made out of sodium.
does it have an atmosphere
Mercury's atmosphere is very thin. The atmosphere of Mercury is mainly made out of sodium. Mercury's atmosphere is so thin because the gases that were there before all got boiled by the sun.
Mercury's atmosphere is MAINLY made up of sodium
Mercury has the thinnest atmosphere of all the planets in our solar system. Mercury's atmosphere is primarily made up of oxygen, sodium, and hydrogen.
Mercury does not have rings and it has no atmosphere.
Mercury has no Atmosphere, unlike Earth, which has an Atmosphere made out of Air. Mercury is dry because their is no water on Mercury.
No. Mercury has a surface made of rock and a large metallic core. It has virtually no atmosphere.
Mercury has a tenuous atmosphere. The atmosphere is made up of water vapor, potassium, calcium, sodium, oxygen, helium and hydrogen.
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.
Mercury does not have an atmosphere.
Mars has almost no atmosphere. APEX=MERCURY has no atmosphere.
