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).

Mercury has a thin atmosphere that is made up of many gases, including: hydrogen, helium, oxygen, calcium, potassium, sodium and water vapor. Mercury is the smallest planet.
No. Mercury does not have an atmosphere.
There are several minor amounts of gases located on Mercury, Examples include methane and krypton. Mercury is the smallest planet in the Solar System.

the reason there are no gases in mercury the molecules moves fast at high temperature
No. Mercury does not have an atmosphere.
Mercury has no atmosphere. Cosmic rays from the sun burn the gases off.
well Mercury has no gas
Mercury is made up of Helium, Hydrogen, and other gases Mercury is made up of Helium, Hydrogen, and other gases
Murcury is made out of gases
There are several minor amounts of gases located on Mercury, Examples include methane and krypton. Mercury is the smallest planet in the Solar System.
none
yes,because mercury is close to the sun...
Mercury's gases escaped into space once
Mercury is made up of Helium, Hydrogen, and other gases Mercury is made up of Helium, Hydrogen, and other gases
