What type of atmospheres do all 8 planets have?

Answer 1

Pluto: 90% Nitrogen, 9% Carbon-Monoxide and 1% Methane Neptune: 74% Hydrogen, 25% Helium and 1% Methane Uranus: 83% Hydrogen, 15% Helium and 2% Methane Saturn: 97% Hydrogen, 3% and 0.05% Methane Jupiter: 90% Hydrogen, 10% Helium and 0.07% Methane Mars: 95% Carbon-Dioxide, 3% Nitrogen and 1.6% Argon Earth: 78% Nitrogen, 21% Oxygen, 0.9% Argon and 0.03% Carbon-Dioxide Venus: 96% Carbon-Dioxide, 4% Nitrogen and 0.02% Water-Vapor Mercury: 80% Hydrogen and 20% Helium

Answer 2

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.

Jupiter's atmosphere is mainly Hydrogen (around 90%), Helium (around 10%), with small amounts (minor gases) of Methane (around 0.3%), Ammonia (0.026%), Hydrogen Deuteride (0.003%), Ethane (0.0006%) and Water vapour (0.0004%).

Saturn's atmosphere is mainly Hydrogen (around 96%), Helium (around 3%), with small amounts of Methane, Ethane and Ammonia.

Uranus' atmosphere is mainly Hydrogen (around 83%), Helium (around 15%) and Methane (around 2.3%).

Neptune's atmosphere is mainly Hydrogen (around 80%), Helium (around 19%) and Methane (around 1%).

Answer 3

There are a variety of atmospheres in our solar system. Only the Earth has an oxygen and nitrogen atmosphere. Mercury and Mars have almost no atmosphere, just a trace, and no free oxygen. Venus has a very dense, corrosive atmosphere, with a lot of carbon dioxide and sulfuric acid. The gas giants, Jupiter, Saturn, Uranus, and Neptune, have a lot of hydrogen, ammonia, and methane in their atmospheres. The moons of the outer planets have hydrocarbon atmospheres.

Answer 4

There are a wide range of atmospheres for terrestrial planets (smaller, rocky planets) depending on their sizes, orbits, and composition.

In our solar system, there are 4 very different atmospheres for the 4 terrestrial planets.

Mercury - no appreciable atmosphere due to small size and closeness to the Sun

Venus - hot, extremely dense carbon dioxide atmosphere (Greenhouse effect)

Earth - cool, low density nitrogen atmosphere, oxygen maintained by green plants

Mars - very thin, cold carbon dioxide atmosphere, due to small size and distance from the Sun
