What gases is mercury the planet made of?

Answer 1

Mercury's atmosphere is made up of the gases oxygen, hydrogen, helium, carbon dioxide and trace amounts of argon, xenon, and nitrogen. This rocky planet has a very thin atmosphere, and it is the nearest planet to the sun.

Answer 2

Mercury's atmoshere dissipated shortly after the planet's formation because of both the low level of gravity on the planet, the high temperature, and the effects of the solar wind. However, at present there are traces of atmosphere containing small amounts of the gasses hydrogen, helium and oxygen.

Mercury does not have enough gases in its atmosphere to reduce the amount of heat and light it receives from the sun. The temperature on the planet may reach 840 degrees F (450 degrees C) during the day. But at night, the temperature may drop as low as -275 degrees F (-170 degrees C). Because of the lack of atmosphere, Mercury's sky is black. Stars probably would be visible from the surface during the day. Scans of Mercury made by Earth-based radar indicate that craters at Mercury's poles contain water ice. The floors of the craters are permanently shielded from sunlight, so the temperature never gets high enough to melt the ice. Mercury is surrounded by an extremely small amount of helium, hydrogen, oxygen, and sodium. This envelope of gases is so thin that the greatest possible atmospheric pressure (force exerted by the weight of gases) on Mercury would be about 0.00000000003 pound per square inch (0.000000000002 kilogram per square centimeter). The atmospheric pressure on the Earth is about 14.7 pounds per square inch (1.03 kilograms per square centimeter).

It has no atmosphere
Mercury is the fourth planet from the Sun in the Milkey Way galaxy. The dominant atmospheric gas is carbon dioxide, which makes up 95% of the atmosphere.
42% Molecular oxygen.

This answer seems unlikely because Mercury has no atmosphere as far as

I know.

Answer 3

Mercury doesn't have any significant amount of gases.

Answer 4

Mercury's atmosphere is primarily composed of oxygen, sodium, hydrogen, helium, and potassium. However, it is very thin compared to other planets in our solar system.

Answer 5

Mercury has almost no atmosphere at all.
