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 planet has the least amount of craters due to is protective atmosphere?
Venus has a very dense atmosphere, which helps burn up many meteors it pulls in. This lets the planet have many less craters than others. Additionally, the gas giants don't have any known craters, since they are made of mostly gas.
What planet is the moon most like?
Mercury is the planet that most resembles the Moon in visible surface features and atmosphere. It is a grey planet that has many craters and a thin atmosphere.
What celestial bodies is most likely to have many craters?
Any fairly large rocky body with no atmosphere. In our solar system, the Moon and Mercury both fit this description.
Will a planet with active volcanoes have more or fewer craters than a planet without active volcanoes?
A planet with active volcanoes will have fewer craters, as older craters will tend to be buried by lava and ash.
Is mercury dry and have craters like the moon?
First ,the presence of craters on Mercury. Yes these are present and have been confirmed by NASA photographs. These craters are created by similar processes as those on the moon.Mercury has water ice in shadowed craters at its north pole. This was identified by radar examination of the planet in 1994 and later confirmed by NASA photographs.Similarly water ice has been identified in shadowed craters at the moon's poles.As a consequence:Mercury is not dry, it has ice depositsMercury has craters formed by impacts like those on the moon.Some of the craters in both locations are dry (the majority) Others have ice deposits.

Was there any craters on the moon?
Yes, there are craters on the Moon. Any planet with a solid surface and not too much of an atmosphere will have craters.
What planet is full of impact craters and and no atmosphere?
I think it is Mercury.
What planet is the moon most like?
Mercury is the planet that most resembles the Moon in visible surface features and atmosphere. It is a grey planet that has many craters and a thin atmosphere.
What is the relationship between the number of craters and the thickness of a planet's atmosphere?
The thinner the atmosphere, the more craters the planet has. Planets with thicker atmospheres burn up most asteroids before they hit the ground.
How would you tell that a planet or a moon had no atmosphere just by looking at the surface?
If there are lots of craters, it means there is no significant atmosphere. The reason is that any craters will be eroded eventually, by the presence of an atmosphere.
True or false craters on mercury surface are eroded only very slow this planet has a sulfuric acid atmosphere?
False. Craters are not eroded on Mercury, which has no atmosphere.
What has many craters no atmosphere?
Mercury.
What celestial bodies is most likely to have many craters?
Any fairly large rocky body with no atmosphere. In our solar system, the Moon and Mercury both fit this description.
What planet is most covered with craters?
Mercury. It has a lot of craters as the planet has no atmosphere to speak of and therefore no weather. Meteors are allowed to collide with the planet a lot more easily as the lack of atmosphere means that they don't burn or break up, the lack of weather also means that the craters stay put once they are formed, much like on our moon. There are also no active volcanoes to cover matter over the formed craters.
Which terrestrial planet has no craters?
There is no terrestrial planet without craters.
Is Venus' made of dust?
Venus is a rocky planet with a very thick atmosphere due to greenhouse gasses. Many volcanos and craters also are abundnt on Venus.
