Jupiter
Definition
Jupiter is the largest planet in our solar system. It has a diameter of 139,820 kilometres, which is more than 11 times the diameter of Earth. Jupiter is also the most massive planet in our solar system, with a mass of 1.9e27 kilograms, which is more than 318 times the mass of Earth.
Jupiter is a gas giant, which means that it is made up mostly of hydrogen and helium. It has a very thick atmosphere, which is made up of clouds of ammonia and methane. Jupiter also has a Great Red Spot, which is a giant anticyclonic storm that has been raging for centuries.
Jupiter has a strong magnetic field, which is generated by its rapidly rotating core. This magnetic field traps charged particles from the solar wind, creating a large magnetosphere around Jupiter. The magnetosphere is so large that it extends far beyond the orbit of Saturn.
Jupiter has a system of moons, which are thought to have formed from the debris left over from a collision between Jupiter and another planet. Jupiter has 80 confirmed moons, and it is possible that there are many more moons that have not yet been discovered.
The largest moon of Jupiter is Ganymede, which is larger than the planet Mercury. Ganymede has a thick atmosphere and an icy surface. It is thought to have a liquid ocean beneath its surface.
Jupiter is a fascinating planet, and it is still being studied by scientists today. We are learning more about Jupiter all the time, and it is sure to continue to surprise us for years to come.
How can the word be used?
The ancient Romans worshipped Jupiter as the god of the sky and thunder.
Different forms of the word
The word "Jupiter" has two main forms:
Jupiter: This is the most common form of the word. It is the name of the largest planet in the Solar System. It is also the name of the Roman god of the sky and thunder.
Jove: This is an older form of the word. It was used by the ancient Romans to refer to the god Jupiter. It is still sometimes used poetically or in reference to mythology.
Etymology
The word "Jupiter" comes from the Latin word "Jovis", which was the name of the Roman god Jupiter. The word "Jovis" is thought to be derived from the Proto-Indo-European word "Dyeus", which means "sky father".
The name Jupiter was given to the planet because it was the largest planet known to the ancient Romans. They believed that it was the home of the god Jupiter, and they often used the planet as a symbol of power and authority.
The name Jupiter is still used today to refer to the planet. It is also sometimes used poetically or in reference to mythology.

AQA Science Exam Question and Answer
Question:
Describe the key characteristics and significance of the planet Jupiter in our solar system. Explain the role of Jupiter as a "gas giant" and its impact on the solar system dynamics.
Answer:
Jupiter, the largest planet in our solar system, possesses distinctive characteristics that make it a significant celestial body. It is classified as a gas giant due to its composition predominantly made up of hydrogen and helium, unlike rocky planets like Earth. Its immense size allows it to have a powerful gravitational pull, influencing the movement of other planets and objects in the solar system.
Jupiter's most prominent feature is its Great Red Spot, a massive storm system that has persisted for centuries. This storm is larger than Earth and showcases Jupiter's turbulent atmosphere. Its many moons, including the four largest known as the Galilean moons (Io, Europa, Ganymede, and Callisto), are of great interest to scientists due to their unique characteristics, such as potential subsurface oceans.
As a gas giant, Jupiter's influence on the solar system dynamics is significant. Its massive gravity affects the orbits of nearby planets and helps shield the inner solar system from some potentially hazardous comets and asteroids by redirecting their trajectories.
Overall, Jupiter's status as a gas giant and its distinct features contribute to its role as a fascinating object of study. Its gravitational influence and interactions with other celestial bodies continue to shape the dynamics of our solar system.
