What the atmospheric of mercury?
Mercury's atmosphere contains small amounts of hydrogen, helium, and oxygen. It also has even tinier amounts of sodium, potassium, calcium, and magnesium. Some of the gas particles come from the solar wind. Others are made by radioactive decay or when micrometeorites smash into the surface.

Mercury does not have much of an atmosphere as its gravity is tooweak to keep one. However it does have a very unstable tenuous onecontaining hydrogen, helium, oxygen, sodium, calcium and potassium. So far, observations of Mercury from ground-based observers and theMariner 10 spacecraft have not sh…own evidence of a significantatmosphere compared to other planets. Mariner 10 did observe a tinyamount of helium 1000 km above the surface, but this is probablycaused by the solar wind and the breakdown of Mercury's crust.Sodium, potassium and oxygen have also been detected in Mercury'svery weak atmosphere, but these elements can be lost when theyreact with the Sun and Mercury's magnetic field. There are no living things on Mercury due to it's sustained hightemperature. (MORE)
Mercury does not have what we would call an atmosphere. It is very, very thin , a collection of a few atoms per cubic meter, some being ionized from the surface. It is less than a trillionth of Earth's.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
Its low mass has made it hard for it to retain any gases at all as an atmosphere
Mercury has the thinnest atmosphere of all the planets in our solarsystem. Mercury's atmosphere is primarily made up of oxygen,sodium, and hydrogen.
Mercury's atmosphere contains: hydrogen, helium, oxygen, sodium,calcium, potassium, and water vapor. Sunlight pushes the gassesaway from the sun, which creates a comet-like tail behind theplanet.
Mercury is unable to retain an atmosphere because of its tiny mass.It is mass is barely 5.5% of Earth's so it cannot sustain anatmosphere.
Mercury has a very thin exosphere made up of atoms that come fromsolar radiation. it contains helium, hydrogen, sodium, calcium, andoxygen.
The dominant gas on Mercury is oxygen, which makes up 42 percent ofthe planet's atmosphere, followed by sodium, which makes up 29percent. Other gases include hydrogen and helium.
It is much smaller than Earth, so has less gravity to hold an atmosphere. Also, its nearness to the Sun means that many molecules have been blasted away by the solar winds (streams of energetic particles from the Sun).
Yes, but in very small quantities. Very very small quantities, Mercury's atmosphere is basically a vacuum.
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 analysi…s 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.

Mercury has no atmosphere worth mentioning. It's too small to retain an atmosphere, especially that close to the Sun. To the extent that there is ANY atmosphere, it is composed primarily of hydrogen thrown off by the Sun, tenuously held until the Sun blows it away again.
The atmosphere of Mercury consists of helium, oxygen, hydrogen andvery small amounts of magnesium, calcium, potassium and sodium. Theatmosphere of Mercury has virtually no gravity.
Mercury has very high temperatures and is made up of hard rock. Weare like a newborn baby - our planet can't resist such hightemperatures, and that is why we have an atmosphere. Mercury canresist all that from the sun.
Yes, but it is incredibly shallow and thin. It is a collection of molecules near the surface, most ionized by the Sun's radiation. (see related question)
mercury's atmosphere is thin so sound waves don't travel very well and there is little oxygen.
Mercury does not have a breathable atmosphere. There is no planetin our solar system that offers an atmosphere that humans canbreathe.

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).
One word- gravity. Mercury is just simply not massive enough to generate the gravity required to hold gases close enough to the surface to create an atmosphere.
mercury's atmosphere is thin so sound waves do not travel very well and there is little oxygen.
No, the atmosphere is very thin. "Mercury has a very thin atmosphere consisting of surface atoms blasted off its surface by the Solar wind. Because Mercury is so hot, however, these atoms quickly escape into space. Thus, in contrast to the Earth and Venus whose atmospheres are stable, Mercury's a…tmosphere is constantly being replenished." (MORE)
Due to its small size and proximity to the Sun, it has an extremely thin atmosphere. Mercury has such a thin atmosphere that it is generally considerednot to have one at all.
Pluto and Mercury have a very small mass and so a weak gravitational field, too weak to hold enough gas to create an atmosphere.

Mercury has almost no atmosphere. The planet's small size means that its gravity is too weak to hold down a normal atmosphere. There is a very thin atmosphere around the planet. Mercury's thin atmosphere is constantly being "blown away" into space by the pressure of sunlight and by the solar wind.… Gases are constantly being added to Mercury's atmosphere, too. That's why it still has any atmosphere at all - even though that atmosphere is really, really thin. Mercury's atmosphere contains small amounts of hydrogen, helium, and oxygen. It also has even tinier amounts of sodium, potassium, calcium, and magnesium. Some of the gas particles come from the solar wind. Others are made by radioactive decay or when micrometeorites smash into the surface. All of these gases are soon carried away from Mercury by the solar wind and by Mercury's magnetic field. Atmospheric pressure at the planet's surface is less than one trillionth of Earth's (around one nanopascal or 10 -14 bar). Temperatures at the surface range between 100 and 700 kelvins (-280Â° F to 800Â° F or -173Â° C to 427Â° C). Lead melts at 600 kelvins! This large range in surface temperature is possible because Mercury is so close to the Sun (a year is only 88 Earth days long) and does not have sufficient atmosphere present to moderate the range in surface temperature.

Titan, Saturn's largest moon, is the only moon in our solar system with its own atmosphere. It (and Jupiter's Ganymede) are both larger than Mercury. I believe the surface gravity on each is less than that of Mercury, however. Not absolutely certain of this. I saw Titan for the first time earlier… this year, through our astronomy club's new 14" telescope. (MORE)
0.9831 atmosphere = 747.156 millimeters of mercury . 1 atmosphere = 760 millimeters of mercury
Mercury's weak gravity and close proximity to the hot sun make iteasy for gasses to escape.
There is no atmosphere in Mercury due to the the combination of twofactors: 1) Due to the high average temperature on Mercury makes individualmolecules of the atmosphere move very fast. 2) The low gravity (to be more precise: escape velocity) makes iteasy for molecules in the atmosphere to escape. …In summary, if anyatmosphere develops on the planet (for example, something leakingout of the ground), it won't last long.

Because their small mass makes its gravity too weak to retain much gas around it. ;-)
There isn't a whole lot going on in the atmosphere of Mercury. It was unclear if Mercury actually had an atmosphere or not until '74 when Mariner 10 discovered an exosphere (an extremely thin atmosphere) around Mercury. Some of the elements that are in this exosphere are hydrogen, helium, oxygen, so…dium, calcium and potassium. There is also a small trace amount of water vapor that is so hot that it will never be able to condense on the surface. Also, Mercury is so close to the sun that there is a comet like tail called a coma coming off of the surface of Mercury in the direction opposite that of the sun. (MORE)
no, it's way too close to the sun to hold onto an atmosphere without the sun's gravity riping it apart, plus the solar winds are too strong for mercury to hold it's atmosphere.
The lack of atmosphere on mercury means that it's surface temperature has a much greater range. It will cool down to below -170 degrees out of the sun, but as high as 500 degrees or so in the sun. There is also no wind or weather on mercury, so craters can survive for millions of years as they do on… the moon. (MORE)
Mars has the next thinnest atmosphere, a thin carbon dioxide atmosphere. Although thin, it's much more substantial than anything mercury has got in the way of surface pressure.
Mercury has no significant atmosphere. Very small traces of gas have been discovered and that's all.
Mercury has no atmosphere, it is not massive enough to hold on to one, nor does it produce a magnetosphere to protect it from solar winds (which would blow away any atmosphere it could otherwise maintain).
Mercury is close to the sun, so any particles which make up the atmosphere would be fried because of the intense heat
Because it is too small and light. It does not have sufficient gravitational pull (which is proportional to mass) to keep its own atmosphere - the gases just escape.

Basically there isn't one. The sun's heat got rid of all the gasses and possible volatiles long ago, the best you could even hope for is a trace of the heavier noble gasses (such as radon).
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.
1. Mercury is close to the Sun. This gives any gas atoms, etc fairly high velocities, with only Mercury's fairly weak gravitational field to hold onto the gas. 2. Venus does have an atmosphere. It is much denser than Earth's atmosphere.
Mercury has no real atmosphere and the temperature on the surface is from 80,000 to 700,000 degrees.
yes, but it is almost nonexistent. What there is consists of 42% oxygen, 29% sodium, 22% hydrogen, 6% helium, 0.5% potassium, and 0.5% other elements.
There are in fact 5 gasses you can choose from that are inMercury's atmosphere. Oxygen, sodium, helium, potassium, andhydrogen.
