as far as we have been able toobserve from ground based observatory's and the Mariner 10 spacecraft, Mercury has not shown evidence of a significant atmosphere. A minute amount of helium was detected by Mariner 10 at about 1000 km above the surface, but this was probably caused by the solar wind and the breakdown of Mercury's crust. Sodium, potassium and oxygen were also detected in Mercury's very weak atmosphere, however these elements can be lost when they react with the Sun and Mercury's magnetic field.
Temperatures on Mercury's surface can reach 430 degrees Celsius (800 degrees Fahrenheit). Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to -170 degrees Celsius (-280 degrees Fahrenheit).
I think that there has been some SO2 outgassing detected. Other than that its a hard vacuum.
Mercurys atmospere contains: Helium, Sodium, Potassium, and Oxygen.
The atmosphere of Mercury is made out of hydrogen,helium,oxygen,sodium,calcium,and potassium.
mercury does not have a atmosphere
there is not any air on mercury
No atmosphere
Venus has a thick atmosphere. Mercury does not have an atmosphere.
No, Mercury doesn't even have an atmosphere.
No. Mercury does not have an atmosphere.
0.9831 atmosphere = 747.156 millimeters of mercury1 atmosphere = 760 millimeters of mercury
it is a very thin atmosphere of oxygen, potassium, and sodium vapors
Mercury does not have an atmosphere.
Mars has almost no atmosphere. APEX=MERCURY has no atmosphere.
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
Mercury and the Moon do not have significant atmospheres. Mercury's thin exosphere mainly consists of atoms blasted off its surface by the solar wind, while the Moon has virtually no atmosphere, making them both airless bodies in our solar system.
