Saturn

Pluto

Jupiter

The celestial body referred to as the "King of the Planets" is Jupiter. This designation arises from its status as the largest planet in our solar system. Jupiter's sheer size is impressive; it has a diameter of about 86,881 miles (139,822 kilometers), making it over 11 times wider than Earth. Additionally, it has a significantly greater mass, containing more than twice the mass of all the other planets combined.

Jupiter's prominent features, including its Great Red Spot (a massive storm larger than Earth) and its extensive system of moons, as well as its strong magnetic field, contribute to its notable position among the planets. The name "King of the Planets" reflects not only its size but also its prominent role in the solar system's dynamics and its visibility from Earth.
