The rate at which solar radiation reaches a unit of area in space in the region of the Earth's orbit is: 1,366 W/m².\n\nDistance from the Sun:\n- Earth's orbit: RE = 1 AU (Astronomic Unit) = 1.496*10^11 m\n- Jupiter's Orbit: RJ = 5.20 AU = 7.7792*10^11 m\n\nIf energy is proportional to 1/r²:\nrate of solar radiation at Earth: SE = k/(RE)² = 1,366 W/m²\nrate of solar radiation at Jupiter: SJ = k/(RJ)² = ????\n\ncombining equations:\nSJ = (1.496*10^11 m)²(1,366 W/m²)/(7.7792*10^11 m)²\nSJ = 50.51 W/m²

I would say Europa and titan. Europa is unlike any other body in the solar system, it is not jupiters smallest moon rather the smallest of the galilean moons of jupiter with a diameter of 3100km. Its surface is among the brightest in the solar system, a consequence of sunlight reflecting off a relatively young icy crust. \n\nIts face is also among the smoothest, lacking the heavily cratered appearance characteristic of Callisto and Ganymede. Lines and cracks wrap the exterior. if you were to scale Europa down it would probably be a smooth as a billiard ball. Scientists believe that beneath Europa's icy surface lies a liquid ocean which has the possibility of harbouring life. Let me make myself clear, we're not talking about intelligent life, but rather life that could be very similar to what is found at the bottom of our oceans. \n\nEuropa has a very tenuous atmosphere which is mostly made up of oxygen. Unlike oxygen on Earth however, which is created as a byproduct of photosynthesis in plants, oxygen on Europa is likely to originate when charged particles from the Sun hit water molecules on Europa’s surface. The water molecules are broken into hydrogen and oxygen atoms, and sometimes recombine to form hydrogen and oxygen gas. This kind of environement would make it an ideal habitat for life and very interesting for exobiologists.\n\nTitan would also be extremely interesting to exobilogists.It is the only moon in our solar system with a very thick atmosphere and  like Earth's atmosphere, the atmosphere on Titan is mostly made up of nitrogen. Unlike Earth however it is inhospitable to life due to the lack of atmospheric oxygen and its extremely cold surface temperatures (-183 degrees Celsius) . \n\nAlong with nitrogen, Titan's atmosphere contains a significant amount of methane. The only thing missing for Titan is a little bit of heat. What we know for sure is that the sun is getting warmer by approximately 10% a year. What this means is that in the future, the sun will begin to warm the surface of Titan and therefore give it the possibility of giving birth to life. With the amount of methane in its atmosphere a fair amount of heat would become trapped as methane is a very powerful greenhouse gas.\n\nHope this has helped you out :)

Yes.  There is a very small amount of matter that enters the atmosphere from space (meteorites), but essentially it is all just being recycled. Some atoms of oxygen you breathe in may have been breathed by a dinosaur, or one of the pharoahs!

The highest wind speeds in Jupiter's Little Red Spot have increased and are now equal to the Great Red Spot, which is about 400 miles per hour. I already knew that but you probably would want some official source to what I said...

Jupiter is 2.5 times more massive than all the other planets combined. It is 318 times more massive than Earth, with a diameter 11 times that of Earth, and its volume is 1300 times as great as that of Earth.

Mercury has no true atmosphere.  It only has trace amounts of whatever gases are present.  See the given link.

I have no idea what you are asking.  Argon is 0.934% of the atmosphere.  Is that what you wanted?

The Earth's atmosphere has no definite boundary, slowly becoming thinner and fading into outer space. Three-quarters of the atmosphere's mass is contained within the first 11 km of the planet's surface. This lowest layer is called the troposphere. Further up, the atmosphere is usually divided into the stratosphere, mesosphere, and thermosphere. Beyond these, the exosphere thins out into the magnetosphere (where the Earth's magnetic fields interact with the solar wind). An important part of the atmosphere for life on Earth is the ozone layer.\n\nThe atmospheric pressure on the surface of the Earth averages 101.325 kPa, with a scale height of about 6 km. It is 78% nitrogen and 21% oxygen, with trace amounts of other gaseous molecules such as water vapor. The atmosphere protects the Earth's life forms by absorbing ultraviolet solar radiation, moderating temperature, transporting water vapor, and providing useful gases. The atmosphere is one of the principal components in determining weather and climate.\n\nBecause hydrogen gas is light and based on Earth's mean temperature, achieves escape velocity, unfixed hydrogen leaves the Earth. For this reason, the Earth's environment is oxidizing, with consequences for the chemical nature of life which developed on the planet.\n\nYou could get more information from the link below...

Jupiter is the largest planet in the solar system. Its diameter is 88,846 miles (142,984 kilometers), more than 11 times that of Earth, and about one-tenth that of the sun. It would take more than 1,000 Earths to fill up the volume of the giant planet. When viewed from Earth, Jupiter appears brighter than most stars. It is usually the second brightest planet -- after Venus.\n\nJupiter is the fifth planet from the sun. Its mean (average) distance from the sun is about 483,780,000 miles (778,570,000 kilometers), more than five times Earth's distance. Ancient astronomers named Jupiter after the king of the Roman gods.\n\nAstronomers have studied Jupiter with telescopes based on Earth and aboard artificial satellites in orbit around Earth. In addition, the United States has sent six space probes (crewless exploratory craft) to Jupiter.\n\nAstronomers witnessed a spectacular event in July 1994, when 21 fragments of a comet named Shoemaker-Levy 9 crashed into Jupiter's atmosphere. The impacts caused tremendous explosions, some scattering debris over areas larger than the diameter of Earth.\n\nPhysical features of Jupiter\n\nJupiter is a giant ball of gas and liquid with little, if any, solid surface. Instead, the planet's surface is composed of dense red, brown, yellow, and white clouds. The clouds are arranged in light-colored areas called zones and darker regions called belts that circle the planet parallel to the equator.\n\nOrbit and rotation\n\nJupiter travels around the sun in a slightly elliptical (oval-shaped) orbit. The planet completes one orbit in 4,333 Earth days, or almost 12 Earth years.\n\nAs Jupiter orbits the sun, the planet rotates on its axis, an imaginary line through its center. The axis is tilted about 3¡. Scientists measure tilt relative to a line at a right angle to the orbital plane, an imaginary surface touching all points of the orbit.\n\nJupiter rotates faster than any other planet. It takes 9 hours 56 minutes to spin around once on its axis, compared with 24 hours for Earth. Scientists cannot measure the rotation of the interior of the giant planet directly, so they have calculated the speed from indirect measurements. They first calculated the speed using an average of the speeds of the visible clouds that move with interior currents, except for a more rapid zone near the equator.\n\nJupiter sends out radio waves strong enough to be picked up by radio telescopes on Earth. Scientists now measure these waves to calculate Jupiter's rotational speed. The strength of the waves varies under the influence of Jupiter's magnetic field in a pattern that repeats every 9 hours 56 minutes. Because the magnetic field originates in Jupiter's core, this variation shows how fast the plant's interior spins.\n\nJupiter's rapid rotation makes it bulge at the equator and flatten at the poles. The planet's diameter is about 7 percent larger at the equator than at the poles.\n\nMass and density\n\nJupiter is heavier than any other planet. Its mass (quantity of matter) is 318 times larger than that of Earth. Although Jupiter has a large mass, it has a relatively low density. Its density averages 1.33 grams per cubic centimeter, slightly more than the density of water. The density of Jupiter is about 1/4 that of Earth. Because of Jupiter's low density, astronomers believe that the planet consists primarily of hydrogen and helium, the lightest elements. Earth, on the other hand, is made up chiefly of metals and rock. Jupiter's mix of chemical elements resembles that of the sun, rather than that of Earth.\n\nJupiter may have a core made up of heavy elements. The core may be of about the same chemical composition as Earth, but 20 or 30 times more massive.\n\nThe force of gravity at the surface of Jupiter is up to 2.4 times stronger than on Earth. Thus, an object that weighs 100 pounds on Earth would weigh as much as 240 pounds on Jupiter.\n\nThe atmosphere of Jupiter is composed of abou

Oxygen = O\nNitrogen = N\nCarbon Dioxide = CO2\n\nThey take up the space that is allowed them by the gravity and temperature of the planet, but oxygen and nitrogen form the main two constituents of the atmosphere.

Your density will be similar to whatever material makes up the planet.  For instance, Mars is mostly rock, with some iron ore.  I'd guess the density is on the order of 2.5 g/cm3.  Jupiter is made up of mostly dense gases.  I'd guess given the temp, that the density is slightly higher than that of water, like 1.3 g/cm3.\n\nVolume on the other hand.......are you kidding?  You seriously want it in cm3????  You'll run out of room on your paper writing zeros.

Jupiter is further from the sun, and has a larger orbital path.  That is why it takes longer (it has to travel further to go around)

It is actually a lot less than 1% b/c argon, carbon dioxide, methane, & others all share the last percent. Most of the atmosphere is 78% Nitrogen & 21% Oxygen.\n\nWater vapor is actually variable. It's content changes depending on location, incoming air masses, etc. But still it stays under one percent.

Like the person said above.  0.038% of the atmosphere is made up of CO2.  That's 3.8 parts per million.  So that's why it won't take very much for people to double the amount of CO2 that is naturally occuring.
