Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

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.

What is the atmosphere like on Mercury?

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 (MORE)

Does Mercury have an atmosphere?

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.

What is mercurys atmosphere?

it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.

What is mercurys atmosphere made of?

Mercury has the thinnest atmosphere of all the planets in our solarsystem. Mercury's atmosphere is primarily made up of oxygen,sodium, and hydrogen.

What gases are in the atmosphere of Mercury?

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.

Why does Mercury have no atmosphere?

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).

What is the composition of the atmosphere on Mercury?

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 (MORE)

What are the gases in the atmosphere on Mercury?

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.

What is mercurys atmosphere made out of?

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.

Why is atmosphere absent in mercury?

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.

Is there an atmosphere on Mercury?

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)

What are the main gases in the atmosphere of mercury?

42% Molecular oxygen 29.0% sodium 22.0% hydrogen 6.0% helium 0.5% potassium Trace amounts of argon, nitrogen, carbon dioxide, water vapor, xenon, krypton, & neon[3] Improvement : As far as I know Mercury has no significant atmosphere.

Atmosphere of planet Mercury?

95.72% Carbon dioxide . 2.7% Nitrogen 1.6% Argon 0.2% Oxygen 0.07% Carbon monoxide 0.03% Water vapor 0.01% Nitric oxide 2.5 ppm Neon 300 ppb Krypton 130 ppb Formaldehyde 80 ppb Xenon 30 ppb Ozone . 10 ppb Methane

What is the atmosphere of the planet mercury?

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).

Why doesn't Mercury have an atmosphere?

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.

Does mercury have a dense atmosphere?

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 (MORE)

Does the planet Mercury have 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. (MORE)

What moon larger than Mercury and has atmosphere?

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 (MORE)

Why is there no atmosphere in Mercury?

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. (MORE)

What gasses contain in the atmosphere of mercury?

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 (MORE)

What happens to mercury because it doesnt have an 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 (MORE)

Why does mercury not have atmosphere?

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.

What does Mercury atmosphere consist of?

42% Molecular oxygen 29.0% sodium 22.0% hydrogen 6.0% helium 0.5% potassium Trace amounts of argon, nitrogen, carbon dioxide, water vapor, xenon, krypton and neon

What is the atmospheric like on mercury?

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).

What is in the planet mercurys atmosphere made of?

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.

Why do Mercury and Venus not have an 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.
