Answer:
Mercury, Earth, Jupiter, Sun
Step-by-step explanation:
The order of the celestial bodies in our solar system based on their size is determined by their diameter (or radius). Mercury is the smallest planet in our solar system, with a diameter of about 4,880 km. Earth is larger than Mercury, with a diameter of about 12,742 km. Jupiter is much larger than both Mercury and Earth, with a diameter of about 139,822 km. The Sun is the largest celestial body in our solar system, with a diameter of about 1,391,000 km, which is more than 100 times larger than Jupiter and about 109 times larger than Earth. Therefore, the correct order is Mercury (smallest), followed by Earth, Jupiter, and then the Sun (largest).
