Which planet is known as the largest planet in the solar system?

Jupiter is known as the largest planet in the solar system due to its immense size and mass. It has a diameter of about 86,881 miles (139,822 kilometers) and is primarily composed of hydrogen and helium. This gas giant has a volume that could contain over 1,300 Earths, highlighting its vast scale compared to other planets. Additionally, Jupiter's strong gravitational pull contributes to its ability to maintain a large number of moons and even capture smaller celestial bodies into its orbit.

The unique characteristics of Jupiter, including its Great Red Spot—a colossal storm that has been raging for centuries—further emphasize its status as the largest planet. Its significant magnetic field and extensive ring system also add to its grandeur. Other planets in our solar system, such as Earth, Saturn, and Mars, while notable in their own right, do not match Jupiter's size or mass, affirming its position as the giant of the solar system.
