Here's why:

* The Sun is a star: It's a giant ball of hot gas that produces its own light and heat through nuclear fusion.

* Saturn is a planet: It orbits the sun and doesn't produce its own light.

In terms of size:

* The sun's diameter is about 1.39 million kilometers (865,000 miles).

* Saturn's diameter is about 120,536 kilometers (74,898 miles).

This means the sun is over 10 times wider than Saturn!
