JUPITER

Size and Composition: Jupiter is the largest planet in our solar system, with a diameter of about 143,000 kilometers (89,000 miles). It is primarily composed of hydrogen and helium, similar to the composition of the Sun, but it lacks the critical mass required to trigger nuclear fusion and become a star.

Great Red Spot: Jupiter is well-known for its iconic feature called the Great Red Spot. It is a persistent high-pressure storm system, appearing as a large reddish-colored oval on the planet's surface. The Great Red Spot is a centuries-old storm that is larger than Earth itself.
