In a scale model of the solar system, Jupiter should compare to Mercury by being significantly larger, as Jupiter is the largest planet in our solar system, while Mercury is the smallest.
The correct response is: It will be thirty times the size.
This approximation aligns with the actual diameters of the planets, where Jupiter’s diameter is about 11 times that of Earth, while Mercury's diameter is about 0.4 times that of Earth. In a scaled comparison, Jupiter would indeed be roughly 30 times larger than Mercury.
