Jupiter Questions and Answers (Q&A)

Jupiter’s moon Europa is often thought of as possible abode for life, because of the potential liquid water ocean beneath its icy surface. Europa has been speculated to be one of the most likely locations in the solar system for potential habitability. Life could exist under the ocean.

Scientists have researched the salt from a subsurface ocean may likely contain geological features on Europa, and this suggests that the ocean is interacting with the seafloor, which might be important in determining if Europa could be habitable.

The Jupiter trojans, frequently called trojan asteroids or just trojans, are a large group of asteroids that share the planets Jupiter's orbit around the sun. They are named for heroes in the ancient Greek tales of the Trojan War. In the Lagrangian Point, the gravity is such that another small object can tag along in orbit without being pulled in or pushed out.

As things aren't getting pushed out of there, they become stuck in there as well, which created large clumps of asteroids in Jupiter's orbit. (Trojan Asteroids). The group ahead of Jupiter is known as the Greek Camp, and the group behind it The Trojan Camp, with asteroids being named after famous people in that ancient war. Together, these two groups have as many asteroids as the asteroid belt.

The requirement of nuclear fusion to occur is possessing enough mass to heat the core of the planet to 10,000 k. Jupiter's mass is too small to create nuclear fusion. Jupiter would need to be about seventy-five times as massive to fuse hydrogen, burn like the sun or become a star.

Jupiter is not big enough to react to the elements helium and hydrogen, which burn and cause it not to become bright, which is because there is no reaction to generate energy to burn. Jupiter is comprised of similar materials as the sun.

New atmospheric data indicates that carbon is abundant in its crystal form. Lightning storms turn methane into the soot (carbon) which as it falls, hardens into chunks of graphite and then diamond. As the clouds of soot fall toward the planet, they clump together to form graphite. As the pressure increases closer to the planet's core, the graphite is compressed into a pure diamond.

These diamond "hailstones" will eventually melt into a liquid sea in the planets hot cores. The largest diamonds would more than likely be about a centimeter in diameter (big enough to put on a ring). When the diamond melts, it forms liquid diamond raindrops.

Jupiter does not have a solid surface and although there is a small solid core, there is nothing like a planetary surface. It is under an enormous pressure caused by the mass of gas that makes up the bulk of the planet. The atmosphere of Jupiter is ninety percent hydrogen. The remaining ten percent is almost wholly made up of helium, though there are small traces of other gases inside. Like the sun, Jupiter is composed of hydrogen and helium.

The atmosphere of Jupiter is ninety percent hydrogen. The remaining ten percent is almost completely made up of helium. These gas layers form layers that extend downward. Because there is no solid ground, Jupiter's surface is defined as the point where the atmospheric pressure is equal to that of Earth. Trying to stand on the surface would be impossible since it is merely another layer of gases.

The moons of Jupiter are so innumerable and diverse that they are broken down into several groups. Jupiter has the most moons of any solar planet. There are seventy- nine known moons of Jupiter. The physical and orbital features of the moons vary widely.

Their orbital shapes range from nearly perfectly circular to highly eccentric and inclined, and many revolve in the direction opposite to Jupiter's spin or retrograde motion. The tiny moons on Jupiter orbit both inside and outside of where the outer moon's orbit, which puts it at risk for collision.

The Great Red Spot, which is the most noticeable feature on Jupiter's surface is a storm about 12,400 miles (20,000 kilometers) wide, about two to three times larger than Earth. Vertical surges hold the key to The Great Red Spot's longevity. The Great Red Spot is a persistent high- pressure region in the atmosphere of Jupiter, producing an anticyclonic storm 22 degrees south of the planet’s equator.

The reason that the storm has continued to exist for centuries is that there is no planetary surface to provide friction (only a liquid core of hydrogen); circulating gas persists for quite a long time in the atmosphere because there is nothing to oppose their angular momentum.

Jupiter has many moons, about 79 known and there are probably many unknown as well. There are four very large moons which are known as the Galilean moons. Ganymede, Callisto, Lo, and Europa, with Ganymede being the largest in our solar system at 5268 km or 3273 miles in diameter, this moon is made up of rock and ice with the temperatures ranging from -171 F to -297 F.

The moon is named after the Trojan prince who was known for his beauty and the Greek translation is Cup bearer to the Gods. Ganymede is about 665,000 miles away from the surface of Jupiter, and it takes approximately 7 Earth days to orbit the planet.

Around the world, you’ll find Jupiter highest up around dusk or nightfall. Jupiter appears to be rather low in the southwest sky at northern latitudes in the southern hemisphere. You can see Jupiter fairly high in the western sky. Jupiter is positioned closer to the setting sun and gets sooner after sundown.

Jupiter remains out longer after sunset in the southern hemisphere. That's because the ecliptic (the pathway of the sun, moon, and planets) hits the evening horizon straight up and down located in the southern hemisphere, yet at a shallow angle in the Northern hemisphere.

Jupiter has the most sizeable planetary atmosphere in the solar system, spanning over 5,000 km (3,000mi) in altitude. Due to the fact that Jupiter has no surface, the base of its atmosphere is typically considered the point at which atmospheric pressure is equal to 100 k Pa (1.0 bar). One bar is 14.5psi. It has been estimated to be between 50 to 100 million times the pressure of earth's atmosphere at sea level. Jupiter's atmosphere is the most voluminous in the solar system.

Molecular hydrogen and helium make -up most of it's it’s atmosphere as well as amounts of ammonia, methane, hydrogen, sulfide, and water. Jupiter's atmosphere is quite impressive. There are cyclones, anticyclones, storms and lightning storms are seen from the earth.
