Here's why:

* Earth's density: Earth has an average density of about 5.52 grams per cubic centimeter (g/cm³).

* Jupiter's density: Jupiter has an average density of about 1.33 g/cm³.

This means that Earth is about 4 times denser than Jupiter.

While Jupiter is much larger than Earth, it's mostly composed of lighter elements like hydrogen and helium, giving it a lower overall density. Earth, on the other hand, has a rocky composition, making it significantly denser.
