What is the composition of the atmosphere of Mercury?

Answer 1

Composition 42% Molecular http://wiki.answers.com/wiki/Oxygen
29.0% http://wiki.answers.com/wiki/Sodium
22.0% http://wiki.answers.com/wiki/Hydrogen
6.0% http://wiki.answers.com/wiki/Helium
0.5% http://wiki.answers.com/wiki/Potassium Molecular oxyen, sodium, hydrogen, helium, potassium

Answer 2

Mercury has no real atmosphere.

However it does have a very unstable tenuous one containing hydrogen, helium, oxygen, sodium, calcium and potassium. These exist in ionized forms in extremely low concentrations, making the atmosphere nearly indistinguishable from the vacuum of space.

One analysis found the following elements, most of which are probably derived from the solar wind, or (like sodium) released from surface materials.

42% molecular oxygen

29% Sodium

22% Hydrogen

6% Helium

5% Potassium

Traces of argon, nitrogen, CO2, water vapor, xenon, krypton and neon.

Answer 3

Mercury has a very unstable tenuous atmosphere containing hydrogen, helium, oxygen, sodium, calcium and potassium. These exist in ionized forms in extremely low concentrations, making the atmosphere nearly indistinguishable from the vacuum of space.

Answer 4

Mercury's atmosphere is very thin and consists mainly of oxygen, sodium, hydrogen, helium, and potassium. It is not conducive to supporting life as we know it due to the lack of significant atmosphere and extreme temperature variations on the planet's surface.

Answer 5

Technically, Mercury has no rings, so that can't be answered.

Answer 6

It is composed of silicates, such as those on Earth and the other inner planets. These are compounds containing silicon, such as silicon oxide (SiO2).

Answer 7

Mercury has no significant atmosphere. Very small traces of gas have been

discovered and that's all.
