How Big Is Jupiter? Its Size Is Massive, but Is It as Dense as Earth?
Our planet Earth flies between the sun and the outer planet Jupiter on May 8 (if you're in the Americas or Pacific) or May 9 (for time zones in the. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars: The planets of the outer solar system are Jupiter, Saturn, Uranus, and Neptune. In short, Jupiter is almost 11 times the size of Earth, and just under of both the Sun and Earth, Earth orbits the Sun in a counterclockwise direction. However, the relationship between temperature and altitude is more.
The atmosphere contains trace amounts of methane, water vapor, ammonia, and silicon-based compounds as well as trace amounts of benzene and other hydrocarbons.

There are also traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine, and sulfur. Crystals of frozen ammonia have also been observed in the outermost layer of the atmosphere. Kelvinsong CC by S. The core has also been inferred as being rocky, but this remains unknown as well. And much like Earth, temperatures and pressures inside Jupiter increase dramatically toward the core. Earth has a very minor orbital eccentricity approx. This works out to an average distance aka.
Planet Jupiter: Facts About Its Size, Moons and Red Spot
The orbits of the inner planets of the Solar System, with Jupiter and the donut-shaped asteroid belt is located between them. Wikipedia Commons The Earth has an orbital period of This means that every four years in what is known as a Leap Yearthe Earth calendar must include an extra day.
Though technically a full day is considered to be 24 hours long, our planet takes precisely 23h 56m and 4 s to complete a single sidereal rotation 0. But combined with its orbital period around the Sun, the time between one sunrise and another a Solar Day is 24 hours. Viewed from the celestial north pole, the motion of Earth and its axial rotation appear counterclockwise. From the vantage point above the north poles of both the Sun and Earth, Earth orbits the Sun in a counterclockwise direction.
In addition to producing variations in temperature, this also results in variations in the amount of sunlight a hemisphere receives during the course of a year.
Meanwhile, Jupiter orbits the Sun at an average distance semi-major axis of , km 5. At this distance, Jupiter takes In other words, a single Jovian year lasts the equivalent of 4, Far from being static, the stripes of clouds change over time. Inside the atmosphere, diamond rain may fill the skies. The most extraordinary feature on Jupiter is undoubtedly the Great Red Spota giant hurricane-like storm seen for more than years.
The color of the storm, which usually varies from brick red to slightly brown, may come from small amounts of sulfur and phosphorus in the ammonia crystals in Jupiter's clouds. The spot has been shrinking for quite some time, although the rate may be slowing in recent years. Jupiter's gargantuan magnetic field is the strongest of all the planets in the solar system at nearly 20, times the strength of Earth's. It traps electrically charged particles in an intense belt of electrons and other electrically charged particles that regularly blasts the planet's moons and rings with a level of radiation more than 1, times the lethal level for a human, damaging even heavily shielded spacecraft such as NASA's Galileo probe.
The magnetosphere of Jupiter, which is composed of these fields and particles, swells out someto 2 million miles 1 million to 3 million km toward the sun and tapers to a tail extending more than million miles 1 billion km behind Jupiter. Jupiter spins faster than any other planet, taking a little under 10 hours to complete a turn on its axis, compared with 24 hours for Earth.
This rapid spin makes Jupiter bulge at the equator and flatten at the poles, making the planet about 7 percent wider at the equator than at the poles. Jupiter broadcasts radio waves strong enough to detect on Earth. These come in two forms — strong bursts that occur when Io, the closest of Jupiter's large moons, passes through certain regions of Jupiter's magnetic field, and continuous radiation from Jupiter's surface and high-energy particles in its radiation belts.
These radio waves could help scientists to probe the oceans on its moons.
Nearly 20, times stronger than Earth's Chemical composition: Jupiter has a dense core of uncertain compositionsurrounded by a helium-rich layer of fluid metallic hydrogen, wrapped up in an atmosphere primarily made of molecular hydrogen.
A core less than 10 times Earth's mass surrounded by a layer of fluid metallic hydrogen extending out to 80 to 90 percent of the diameter of the planet, enclosed in an atmosphere mostly made of gaseous and liquid hydrogen. The four largest moons of Jupiter, now called Io, Europa, Ganymede, and Callisto, were discovered by Galileo Galilei himself, and are appropriately known today as the Galilean satellites.
Ganymede is the largest moon in our solar system, larger even than Mercury and Pluto. It is also the only moon known to have its own magnetic field. The moon has at least one thick ocean between layers of ice, although it may contain several layers of both materials.

Io is the most volcanically active body in our solar system. The sulfur its volcanoes spew out gives Io a blotted yellow-orange appearance that is often compared to a pepperoni pizza. As Io orbits Jupiter, the planet's immense gravity causes "tides" in Io's solid surface that rise feet meters high, generating enough heat for volcanic activity.
Jupiter iskilometers in diameter at its equator, but it rotates so fast its day lasts only about 10 hours.
That rapid rotation causes its equatorial diameter to be kilometers more than the distance between its poles. Charged particles from the solar wind, as well as from Jupiter, itself, are trapped in its magnetic field, creating a vast plasma sheath similar to the Van Allen belts around Earth. The plasmasphere around Jupiter emits lethal radiation that is thousands of times greater than the Van Allen belts, however.
Any manned missions would require a spacecraft with heavy shielding. The Galileo spacecraft discovered electric currents flowing around the planet, just as Electric Universe advocates predicted.
The planet has thin rings surrounding it, as well, as do all of the gas giants. The ring structure is quite diffuse, making observations difficult unless they are in correct alignment with the Sun. The outer radius begins atkilometers, almost the same distance as the moon Adrastea. However, as previous Picture of the Day articles about Saturn point out, there is evidence to suggest that electricity is a primary factor in the structure of any ring system.
