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.
Yes, many other planets in our solar system have atmospheres, such as Venus, Mars, Jupiter, Saturn, Uranus, and Neptune. However, the composition and density of these atmospheres vary significantly from planet to planet.
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.
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.
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.
All planets in our solar system have an atmosphere.
However, planets in other systems may have had their atmosphere stripped by other celestial objects.

How does the chemical composition of the terrestrial planet atmospheres differ from the Jovian planets?
Terrestrial planet atmospheres are primarily composed of gases like nitrogen and oxygen, with small amounts of carbon dioxide and other trace gases, while Jovian planet atmospheres consist mostly of hydrogen and helium, along with traces of methane and ammonia. Terrestrial planets have thinner atmospheres compared to Jovian planets, which have massive, thick atmospheres made up of mostly hydrogen and helium.
Could you list the planets in order from the thickest to thinest atmospheres?
The terrestrial planets in order from the thickest to thinnest atmospheres Venus, Earth, Mars, and Mercury. Since the gas giants are almost entirely made of gas, it is difficult to determine where the atmospheres end.
Do outer planets have atmospheres?
Yes
What are the atmospheres of the outer planets like?
Outer planets like Jupiter and Saturn have thick atmospheres composed mostly of hydrogen and helium. Uranus and Neptune have atmospheres rich in frozen ices like water, ammonia, and methane. Strong winds, massive storms, and unique cloud formations characterize the atmospheres of these outer planets.
Which 2 inner planets have thick atmospheres?
Venus and Earth are the two inner planets with thick atmospheres. Venus has a thick atmosphere composed mainly of carbon dioxide, while Earth has a diverse atmosphere containing nitrogen, oxygen, and other trace gases.
Why does other planets in the milky-way does not have life?
They are too hot or too cold. They do not have atmospheres.
Do inner planets have thicker atmospheres than outer planets?
no

Do outer planets have atmospheres?
Yes
What are the atmospheres of all the planets like?
78% nitrogen 20% oxygen 1% of other gases
What has the author J-P Beaulieu written?
J.-P Beaulieu has written: 'Molecules in the atmospheres of extrasolar planets' -- subject(s): Atmospheres, Extrasolar planets, Congresses, Planets
What are effects that atmospheres have on planets?
greenhouse effect
Do any other planets have an atmosphere that shelters it from the sun's rays?
yes, some other planets like Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have atmospheres
Which terrestrail planets have atmospheres?
Venus, Earth and Mars.
What are the atmospheres of outer planets?
its made out of jaffa cakes
How many planets have atmosphere?
Eight planets in our solar system have atmospheres. These planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
