Mars only has a thin atmosphere, mainly of Carbon Dioxide. This is due to its relatively small mass, where the gravity is too low to sustain a large atmosphere. In addition, the absence of a magnetic field around the planet means that the solar wind can more easily strip any gas away from the planet.
Mercury, Mars, and Pluto have thin atmospheres. These planets have atmospheres composed mostly of gas particles that are sparse compared to Earth's atmosphere.
Mars has a thin atmosphere, mainly of Carbon Dioxide. Its surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
Mercury has no atmosphere to speak of; Mars has less than 1% of Earth's and Venus has about 70 times Earth's.
I think it would be Mercury and Mars.

Is Mars made of gas or rock?
No. Mars has a rocky surface and a metallic core.
What are the two planets with no atmosphere?
Mercury and Mars are known as the two planets in our solar system with little to no atmosphere. Mercury's atmosphere is so thin that it's often considered to be nonexistent, while Mars has a thin atmosphere composed mostly of carbon dioxide.
Do all inner planets have a thin atmospheric shell?
No, not all inner planets have a thin atmospheric shell. For example, Mercury has a very thin atmosphere, while Venus, Earth, and Mars have thicker atmospheres. The composition and density of the atmosphere vary for each planet.
What are the two planets in the solar system with no atmosphere?
The two planets in our solar system with little to no atmosphere are Mercury and Mars. Both planets have extremely thin atmospheres compared to Earth, with Mercury's atmosphere consisting mainly of oxygen, sodium, hydrogen, helium, and potassium, and Mars' atmosphere comprised primarily of carbon dioxide.
Compare the atmospheres of the four inner planets?
Mercury has a thin atmosphere mostly made of oxygen, sodium, hydrogen, helium, and potassium. Venus has a thick atmosphere of carbon dioxide with clouds of sulfuric acid. Earth's atmosphere is primarily nitrogen and oxygen with traces of other gases. Mars has a thin atmosphere mainly comprised of carbon dioxide.
Is Mars made of gas or rock?
No. Mars has a rocky surface and a metallic core.
What are the two planets with no atmosphere?
Mercury and Mars are known as the two planets in our solar system with little to no atmosphere. Mercury's atmosphere is so thin that it's often considered to be nonexistent, while Mars has a thin atmosphere composed mostly of carbon dioxide.
Do all inner planets have thick atmospheres?
No. Only Venus has a really thick atmosphere. Mars has only a thin atmosphere and Mercury has almost no atmosphere.
Do all inner planets have a thin atmospheric shell?
No, not all inner planets have a thin atmospheric shell. For example, Mercury has a very thin atmosphere, while Venus, Earth, and Mars have thicker atmospheres. The composition and density of the atmosphere vary for each planet.
Does a dwarf planet have an atmosphere?
Some dwarf planets, like Pluto, have thin atmospheres composed mainly of nitrogen, methane, and carbon monoxide. However, the atmospheres of dwarf planets are not as substantial as those of larger planets like Earth or Jupiter.
What is the difference between a thin and thick atmosphere?
A thin atmosphere has low pressure and density, like on Mars, while a thick atmosphere has higher pressure and density, like on Earth. Thick atmospheres can trap heat and support life, while thin atmospheres make it harder for planets to retain heat and protect against harmful radiation.
Which of the 8 major planets has a thin carbon dioxide atmosphere?
Both Venus and Mars have atmospheres that are mostly carbon dioxide. However, Venus has a very thick atmosphere. The Martian atmosphere is very thin, so the answer is Mars.

Earth's atmosphere is primarily nitrogen and oxygen with traces of other gases. Mars has a thin atmosphere mainly comprised of carbon dioxide.
Is air between planets?
No, there is no air or atmosphere in the vast empty space between planets in our solar system. Space is a vacuum, meaning it is empty of gases and molecules. The thin atmosphere around planets like Earth fades into space as you move away from the planet.
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.
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.
