Which planets do not have an atmosphere?
Each of the eight planets has an atmosphere, though you could argue that Mercury in the exception. Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no real atmosphere due to its small size and proximity to the sun.
Is a comet and a meteor considered to be small planets?
No, comets and meteors are not considered to be small planets. Comets are simply considered to be comets, and meteors are simply considered to be meteors. (Meteors are asteroids that have entered the atmosphere.)
What is Uranus atmosphere like?
The majority of Uranus' atmosphere is made up of hydrogen and helium. It also has a small amount of methane present in the atmosphere.
What planet has many craters but no atmosphere?
There are probably a very great number of planets in our galaxy with no atmosphere. Of the 400+ planets that we know of, we can only determine the presence or absence of an atmosphere for the 8 planets in THIS solar system; our technology is not yet good enough to study atmospheres from several light-years distance. Of the planets of this solar system, we are fairly sure that Mercury has no atmosphere to speak of. Of the other seven, we know that Mars has a very thin atmosphere, but enough to use a parachute in. If we include dwarf planets, we can say with some certainty that Ceres doesn't have enough mass to retain an atmosphere, and Pluto's atmosphere is almost certainly all frozen by now.
Which bodies in the solar system have no atmospheres?
Our Moon, the planet Mercury, and most of the asteroids and dwarf planets are too small to have an atmosphere.
Which of the planets has no atmosphere?
Mercury is the smallest of the eight planets, and is the only one not to have an atmosphere. This is due to its small size and close proximity to the sun.

What is mercurys atmosphere'?
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
Is a comet and a meteor considered to be small planets?
No, comets and meteors are not considered to be small planets. Comets are simply considered to be comets, and meteors are simply considered to be meteors. (Meteors are asteroids that have entered the atmosphere.)
Why do meteoroids hit Mercury but not other planets?
Meteoroids are small enough that they will usually disintegrate when they enter a planet's atmosphere. Mercury has no atmosphere to speak of, and so it is not shielded in this way. Larger asteroids still do strike other planets.
Could you live on dwarf planets?
If you had an enclosed airtight habitat with atmosphere and life support it is technically possible. Dwarf planets are too small to have an atmopshere of their own.
What is Uranus atmosphere like?
The majority of Uranus' atmosphere is made up of hydrogen and helium. It also has a small amount of methane present in the atmosphere.
What is the planet Venus atmosphere?
the atmosphere of palnet venus is mainly contained by; carbon dioxide and a small amount of nitrogen.
Why do all the inner planets have in common?
The inner planets Mercury, Venus, Earth, Mars are are all relatively small, they are all rocky, they all have a relatively thin atmosphere.
What do all the outer planets have in common?
They all have cores, made from gas and dust, have atmosphere's, orbit sun, elliptical orbits.

Do all inner planets have a thin atmospheric shell?
Each of the four inner planets has an atmosphere, except Mercury. Mercury is too small and close to the sun for its gravity to sustain a proper atmosphere, although a tenius and unstable exosphere it thought to exist.
