What is the largest planet in our solar system?

Jupiter is the largest planet in our solar system, and its size is truly impressive. It has a diameter of about 86,881 miles (139,822 kilometers), making it over 11 times wider than Earth. In terms of mass, Jupiter is approximately 318 times more massive than Earth, which contributes to its strong gravitational pull.

Jupiter is classified as a gas giant, composed mostly of hydrogen and helium, and it lacks a solid surface. Its massive size allows it to hold an extensive and complex system of moons—over 79 have been confirmed, including the four largest known as the Galilean moons: Io, Europa, Ganymede, and Callisto.

This unique and massive structure, along with its prominent features such as the Great Red Spot (a gigantic storm), makes Jupiter a fascinating object of study in astronomy and a prominent presence in our solar system. The other planets listed are much smaller in comparison. Mars and Earth are terrestrial planets with solid surfaces, and Saturn, while large and well-known for its spectacular rings, is still smaller than Jupiter.
