What is the largest planet in the Solar System?

Earth
Neptune
Jupiter
Mars

The correct answer is: Jupiter

Jupiter is the largest planet in the Solar System with a radius of over 69,000 km. Earth, on the other hand, has a radius of only 6,371 km. Neptune may seem like a possible answer since it is one of the gas giants, but Jupiter is still larger than Neptune. Mars is the smallest planet among the four choices, with a radius of only 3,390 km. Therefore, Jupiter is the largest planet in the Solar System out of the given options.
