  1. Size and Distance. With a radius of 43,440.7 miles (69,911 kilometers), Jupiter is 11 times wider than Earth. If Earth were the size of a grape, Jupiter would be about as big as a basketball. From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun.

  2. Jupiter's atmosphere is mostly made of molecular hydrogen and helium, with small amounts of other compounds like methane, ammonia, and water. It has four layers: troposphere, stratosphere, thermosphere and exosphere, with different temperature and pressure gradients.

  3. Jupiter’s stunning appearance is due to its atmosphere of swirling clouds and colorful bands, which alternately flow east and west. The atmosphere is mostly hydrogen and helium, but the visible clouds are ammonia. Underneath, there are water clouds. Even after over 200 years, the winds have largely remained unchanged, although the intensity ...

    Jupiteris made up predominantly of hydrogen. The simple, basic gas, a prime ingredient on the sun, accounts for 90 percent of the atmosphere. Nearly 10 percent is composed of helium. A very small fraction of the atmosphere is made up of compounds such as ammonia, sulfur, methane, and water vapor. Traveling from the outermost edges of Jupitertoward ...

    Scientists use changes in the temperature and pressure of the atmosphere to determine the various atmospheric layers. The surface of the planet, or the bottom of the atmosphere, is the point where scientists have calculated that the atmospheric pressure is equal to one bar, the same as found at the surface of Earth. The layer resting on the "surfac...

    In addition to the red and white bands that make Jupiter visually stunning, the planet also boasts a prominent feature known as the Great Red Spot. First identified in the 1600s, the spot is actually a violent storm located just south of the planet's equator. The violent hurricane can be seen from telescopes on Earth. The violent cyclone takes abou...

    A third of the way into the planet, the hydrogen in the atmosphere becomes metallic, allowing it to conduct electricity. This helps to drive Jupiter's powerful magnetic field. The planet rotates rapidly — once every 9.9 hours — and the rapid spinning causes electrical currents in the metallic hydrogen to generate electricity that powers the planet'...

    Jupiter's atmosphere is mostly hydrogen and helium, with traces of other gases and compounds. It has four layers, each with different temperature and pressure, and a powerful magnetic field driven by metallic hydrogen.

  4. Feb 15, 2022 · The atmosphere of Jupiter is 90 percent hydrogen. The remaining 10 percent is almost completely made up of helium, though there are small traces of other gases inside. These gases pile on top of ...

  5. Oct 27, 2023 · Jupiter, the largest planet in our solar system, is most famous for its complex and vibrant Jupiter atmosphere. This gas giant is mainly composed of hydrogen and helium, but the Jupiter atmosphere ...
