Planet Jupiter

The four largest moons of Jupiter, known as the Galilean moons, in order of size from largest to smallest are: Ganymede, Callisto, Io, and Europa. Ganymede is the largest moon in the solar system, even larger than the planet Mercury.

Jupiter has an equitorial diameter of 142,984km. However, you should know that Jupiter, like most planets, is NOT a sphere; a diameter taken across the equator line is significantly longer than a diameter measured from pole to pole.

Yes, water is present on Jupiter in the form of water vapor in its atmosphere. However, due to Jupiter's extreme temperatures and pressure, water exists in a molecular form rather than as liquid or ice on its surface.

"Jupiter's Eye" is a term used to describe a phenomenon called the Great Red Spot on Jupiter. It is a persistent high-pressure region in the planet's atmosphere, resulting in a distinct reddish coloration and a swirling storm system that has been observed for centuries.

Jupiter does not have sandstorms like those found on Earth. Jupiter's atmosphere is made up of mainly hydrogen and helium gases, with no solid surface for sandstorms to occur. Instead, Jupiter's atmosphere experiences powerful winds and storm systems, such as the Great Red Spot.

There is hardly any water in Jupiter's vast atmosphere making humidty almost zero. So astronomers don't exactly have a humidity for Jupiter.

BY the way, if you are interested in Jupiter, Mission Juno will have outcomes in august 2016.

The US space agency's data from a planetary missions shows what appears to be a large body of water beneath Jupiter's ice-covered moon Europa. Similar deposits are thought to be present on Ganymede and Callisto.

Like all space travel, with today's technology, it depends on when you attempt this and how much you are willing to spend. An estimate of the average time at a low cost would be two years to six years depending on the position of the planets in their orbits with respect to one another. What is not possible is a couple of weeks or even months.

Jupiter has been known since ancient times, being visible to the naked eye in the night sky. It was named after the king of the Roman gods and has been observed by various civilizations dating back to at least the Bronze Age.

The jovian planets (Jupiter, Saturn, Uranus, and Neptune) are named after the Roman god Jupiter, who is the king of the gods. This naming convention reflects the grand and powerful nature of these gas giant planets, similar to the grandeur of the king of the gods in Roman mythology.

A year on Jupiter, also known as its orbital period, is approximately 11.9 Earth years. This is the time it takes for Jupiter to complete one orbit around the Sun.

Since Jupiter is a gas planet, it doesn't have a surface. This means that nothing can land on the planet because there is nothing solid to land on. But Jupiter does have its own strange kind of "weather".

The clouds that make up Jupiter are constantly swirling around the planet, driven by winds that average over 322 kilometers. per hour. The winds create an ever-changing pattern of storms. The most famous of these storms is the Great red spot.

Yes, Jupiter is visible from Wales, as it is one of the brightest objects in the night sky and can be easily spotted with the naked eye. Its visibility may be influenced by factors like light pollution and weather conditions, but on clear nights, it can often be seen in the southern sky.

Yes, Jupiter has very minimal axial tilt, which results in no discernible seasons on the planet. This lack of tilt means that its equatorial region receives relatively constant sunlight throughout the year, leading to a consistent climate.

Jupiter holds the record for having the most moons in our solar system, with a total of 79 known moons as of 2021. These moons vary in size and composition, with the four largest being the Galilean moons: Io, Europa, Ganymede, and Callisto.

Jupiter is the large planet known for its Great Red Spot. This massive storm has been observed for over 300 years and is thought to be a high-pressure area in Jupiter's atmosphere.

Yes, you would die if you got too close to Jupiter. Jupiter's intense magnetic field and radiation belts can be lethal to humans. Additionally, the planet's thick atmosphere is composed of mainly hydrogen and helium, which would be toxic to breathe.

No, Io does not have dirt or gravel on its surface. Io is a volcanic moon of Jupiter with a landscape dominated by sulfur and volcanic activity. The surface is covered with sulfur compounds and extensive lava flows, giving it a colorful and dynamic appearance.

Jupiter has a mysterious large red spot known as the "Great Red Spot," which is a massive storm system that has been observed for centuries.

One possible reason may have something to do with the fact that Jupiter is more than five times
as far from the sun as the earth is.

There are other reasons, related to the processes taking place in the core of each planet.
