Well, Jupiter is a gas giant and the largest planet in our system. But, im still confused when you say "heavy" atmosphere can you clarify??
Jupiter's atmosphere is extremelythick.
Jupiter's has a think atmospehere.
Jupiter has a very thick atmosphere composed mainly of hydrogen and helium, along with traces of other gases. This atmosphere is so dense that it becomes increasingly compressed and changes to a liquid-like state deeper within the planet.
Saturn's moon Dione has a thin oxygen atmosphere. Dione, which has large craters, is a relatively small moon, measuring 698 miles in diameter.
Jupiter
Titan, a moon of Saturn, has a thick atmosphere mainly composed of nitrogen. Jupiter's moon Ganymede has a thin atmosphere made up of oxygen.
jupiter and venus are the planets that are heavy and thick that would crush a human.
I think the only candidate for this would be Mars, which has a very thin atmosphere made up of 95% carbon dioxide, 3% nitrogen, 1.6% argon,
Ganymede, Jupiter's moon, has a thin atmosphere composed mostly of oxygen and hydrogen. These gases are present in very low concentrations compared to Earth's atmosphere. Ganymede's tenuous atmosphere is believed to be created by charged particles interacting with the moon's surface.
Unfortunately Jupiter has over 60 known moons. Still, not many have much of an atmosphere. The 4 biggest moons have very thin atmospheres. The details: Callisto : carbon dioxide. Io : sulfur dioxide Europa and Ganymede : mainly oxygen. Remember these are very thin atmospheres.
Jupiter is much warmer than Mars. Jupiter's atmosphere contains gases that trap heat, creating extremely high temperatures throughout the planet. Mars, on the other hand, has a thin atmosphere that does not retain heat well, resulting in much colder temperatures.
Callisto, one of Jupiter's moons, has a very thin and tenuous atmosphere mostly composed of carbon dioxide. However, this atmosphere is too sparse to support life or have any significant effects on the moon's surface.
