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.
The atmosphere on Venus is very thick, giving it a high surface pressure, some 93 times that of the Earths. Carbon Dioxide makes up around 96.5% of the atmosphere with around 3.5% Nitrogen. There are also small amounts of sulfur dioxide (0.0015), carbon monoxide (0.0017%), water vapour (0.002%), argon (0.007), helium (0.0012%) and Neon (0.0007%)
Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, with 0.93% Argon and 0.038% Carbon Dioxide. Around 1% of the atmosphere is water vapour, with traces of other gases such as Neon, Xenon and Carbon Monoxide. Earths atmosphere is thicker than Mars', but not nearly as thick as Venus'.
Mars has a thin atmosphere, mainly of Carbon Dioxide (95.32%). Nitrogen makes up 2.7%, Argon 1.6%, Oxygen 0.13% and Carbon Monoxide makes up around 0.08%. There are other trace gases such as Water Vapour, Neon, Krypton, xenon, Molecular Hydrogen and Nitric Oxide. Mars' surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
What else can I help you with?
What planet has a thick atmosphere has no moon and its rocky?
well there are no planets like that
What is the other type of planet other than gaseous?
The other type of planet is terrestrial, which is made up of mostly rock and metal. Terrestrial planets, like Earth, have a solid surface and a thin atmosphere compared to gaseous planets like Jupiter or Saturn.
What are planets with solid rocky surfaces called?
Planets with solid rocky surfaces are called terrestrial planets. These planets are usually composed of rock and metal, with a thinner atmosphere compared to gas giants. Examples of terrestrial planets include Earth, Mars, Venus, and Mercury.
What feature separates the rocky planets from the gas planets?
Depth of the atmosphere. Gas planets have the thickest and largest of atmospheres. Below gas planets atmospheres are pools of hydrogen or in some cases volatile ices that form in a giant ocean above the surface. It's estimated that Jupiter's rocky surface is only about the size of three Earths but the bloated atmosphere makes for most of the planet.
How many rocky planets are there in the solar?
There are four rocky planets in the solar system: Mercury, Venus, Earth, and Mars.
Which rocky planets have well-developed atmospheres?
Only Earth and Venus has a well developed atmosphere out of the rocky planets. Note that the rocky planets are Mercury, Venus, Earth and Mars.
What type of planet is rocky or gaseous?
The "terrestrial planets" are rocky and the "gas giant planets" are gaseous.
What planet has a thick atmosphere has no moon and its rocky?
well there are no planets like that
Which have well developed atmospheres?
Only Earth and Venus has a well developed atmosphere out of the rocky planets. Note that the rocky planets are Mercury, Venus, Earth and Mars.
Is Mars made of gas or rock?
No. Mars has a rocky surface and a metallic core.
What is the other type of planet other than gaseous?
The other type of planet is terrestrial, which is made up of mostly rock and metal. Terrestrial planets, like Earth, have a solid surface and a thin atmosphere compared to gaseous planets like Jupiter or Saturn.

Planets with solid rocky surfaces are called terrestrial planets. These planets are usually composed of rock and metal, with a thinner atmosphere compared to gas giants. Examples of terrestrial planets include Earth, Mars, Venus, and Mercury.
Is Mercury rocky or gaseous?
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
Which of the rocky planets have well developed atmospheres?
The two largest, Earth and Venus, have a mass large enough to sustain an extensive atmosphere. The other two rocky planets, Mars and Mercury, are too small to hold such an atmosphere. There is some, but it is very thin.
What feature separates the rocky planets from the gas planets?
Depth of the atmosphere. Gas planets have the thickest and largest of atmospheres. Below gas planets atmospheres are pools of hydrogen or in some cases volatile ices that form in a giant ocean above the surface. It's estimated that Jupiter's rocky surface is only about the size of three Earths but the bloated atmosphere makes for most of the planet.
Which rocky planets have well developed atmospheres?
Earth, Venus, and Mars have well-developed atmospheres compared to the other rocky planets in our solar system. Earth has a thick atmosphere that supports life, Venus has a thick and toxic atmosphere, while Mars has a thin atmosphere primarily composed of carbon dioxide.
What is another word for terrestrial planets?
Rocky planets
