Do other planets have atmospheres

Answer 1

Planets defined: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Of these, all except Mercury have an atmosphere. Some atoms of various kinds have been detected near Mercury, suggesting a tenuous exosphere, composed of materials that have been sputtered off the surface by the solar wind. These atoms don't remain very long, and are accelerated away from the planet in a fairly brief period of time.

Answer 2

All except Mercury. Mercury probably doesn't have (much of) an atmosphere because the solar wind would carry it away into space. However, we know very little about Mercury as yet, and won't until the NASA space probe "Messenger" gets into orbit around Mercury in 2011 or so.

Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Answer 3

No because they are made of gas.

Yes, but some of that gas is in fact called their atmosphere. Also the hydrogen

and other stuff might normally be a gas on Earth, but a lot of it is in liquid form.

The high pressure deep inside these planets causes this.

Also there are probably solid parts too, made of "ices" and rock.

The details depend on theory rather than observation, when it comes to the

interiors of these giant planets.

Answer 4

Short answer, yes.

Long answer:

Mercury, the closest planet to the sun, has an atmosphere that is much, much thinner then earth's.

Venus, the second planet from the sun, has a thick atmosphere with large amounts of carbon dioxide. The atmosphere on Venus is so thick and corrosive that only 1 object launched from Earth has been successfully landed on Venus. Durring the 1970's I believe (though I could be wrong on time frame) Russia sent several probes to Venus, most were destroyed in the atmosphere before reaching ground. One successfully landed, and sent back images of a thick yellowish fog, and barren rock. It lasted less then a minute before the corrosive atmosphere destroyed the equipment.

Earth, the 3rd planet from the sun, we know has an atmosphere.

Mars, the 4th planet from the sun, is sometimes called earth's twin. It is significantly smaller, but has much in common with earth. However, its atmosphere is mostly carbon dioxide and much thinner than Earth's.

Answer 5

All planets in our solar system have an atmosphere.

However, planets in other systems may have had their atmosphere stripped by other celestial objects.

Answer 6

i don't specifically know which ones, but yes some do

Answer 7

No. For example, Mercury has no atmosphere to speak of.

Answer 8

no
