They are not the same at all, Venuses atmosphere is very hot dry and thick, while Mars atmosphere is thin and cold. Though they have totally different atmospheres, both planets are going through the same processes, which makes them very similar.
Mars and Venus. But the atmosphere of Venus is many many times denser. Also, all of the outer planets have similar atmospheres. Jupiter and Saturn are a very similar pair and Uranus and Neptune are also two that are very similar.
Mars and Venus are both terrestrial planets in our solar system, meaning they have solid surfaces. They also have similar sizes and compositions, primarily made up of rock and metal. Additionally, both planets have volcanoes and impact craters on their surfaces.
3 Venus,Earth,and Mars (Mercury doesn't have much of an atmosphere there is to less gravity)
Venus, mars.
Venus and Mars. The difference is that Venus atmospheric pressure is around 93 times that of Earths, while Mars' atmospheric pressure is only 0.7% of Earths.
Venus, Earth and Mars.
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.

Mercury doesn't have an atmosphere of any significance. Earth's atmosphere is nothing like the others. That leaves Mars and Venus. They do have similar atmospheres because they both have about 95% carbon dioxide. However the atmosphere of Mars is much thinner than Earth's whereas Venus has a much thicker atmosphere than Earth's.
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.
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.
Venus and Earth share similar size, density, and composition. Jupiter and Saturn both have thick atmospheres and numerous moons. Uranus and Neptune are both ice giants with similar composition and characteristics.
Venus, Earth, Mars, and Triton (Neptune's largest moon) have carbon dioxide in their atmospheres.
On both Venus and Mars, the most abundant gas in the atmosphere is carbon dioxide. On Earth nitrogen is the most abundant gas.
Mars and Venus both have a core which made of metal and they belong to the inferior planets of our solar system.They are also rocky planet like our earth.
