Here's why:

* The Sun is a star, a massive ball of hot gas that produces its own light and heat.

* Jupiter is a planet, a celestial body that orbits a star.

While Jupiter is the largest planet in our solar system, it's still significantly smaller than the Sun. The Sun's diameter is about 109 times larger than Jupiter's diameter. In fact, you could fit over 1,000 Jupiters inside the Sun!
