What is the biggest planet in the solar system? The largest planet in our solar system is the giant called Jupiter. This planet looks amazing and you can see it with binoculars! You don’t even need a powerful telescope to see Jupiter in the night sky. You will be able to see its magnificent color, which is something between yellow, orange and light brown.
On day in Jupiter is ten hours long. This means that Jupiter needs nearly ten hours to rotate around its axis. Jupiter was discovered by Galileo Galilei. He was also the one who spotted Jupiter moons. Today, these moons are called the Galilean moons. Fifty years later, Cassini started observing Jupiter and made some great discoveries about this planet.
How Big is Jupiter?
• Jupiter is very big! We can say that more than 1200 Earths can fit in just one Jupiter. Jupiter is composed of gases. If you wanted to land on Jupiter, it could be impossible, since there is no ground to stand on! You would be swallowed! That means that we can only observe Jupiter, but we cannot examine it closely, as we did with some other celestial bodies. Jupiter’s core is composed of rocks and liquid hydrogen. Storms and hurricanes are common in Jupiter. Some of these storms can last for centuries!
• Another interesting “place” in Jupiter is the Great Red Spot. This spot is actually huge! It is dark red and it can be seen on its surface if you use a telescope. There are no any seasons on Jupiter! Can you imagine that there is only one stormy season all the time?
• Magnetic field of Jupiter is very powerful and strong. When compared to the Earth’s magnetic field, Jupiter’s magnetic field is nearly 20 000 stronger than the Earth’s.
• Jupiter’s moons are especially interesting. There are nearly 63 moons, but four of them are famous. Their names are Europa, Callisto, Io and Ganymede. As we said, Galileo discovered these moons and they are called the Galilean moons. Other well-known moons are Amalthea, Elara, Adrastea, Himalia, Carme, Lysithea, Pasiphae, Leda, Thebe, Metis, Sinope, and many more. Jupiter’s moons are very distant from the planet itself.

• Jupiter rings are also very interesting. They are composed of rocks, some gas and other objects. Jupiter’s major rings are Gossamer and Halo.
• Numerous visits to Jupiter have been carried out, but the most important ones were made by Pioneer, Cassini, Voyager, New Horizons, and Ulysses. The first spacecraft to visit Jupiter was sent in 1973, by NASA.
• Jupiter’s trip around the Sun takes much time. Approximately, it takes nearly 12 years to complete the revolution around the Sun!
• Jupiter is incredibly large, but it rotates very fast. One day in Jupiter is very short.
• Jupiter is one of the brightest celestial bodies, after Venus, Mars and the Sun.
• Gases that Jupiter is composed of include helium, nitrogen and hydrogen. Certain amount of water can be found there, too
