The Sun is approximately 1,000 times bigger than Jupiter in terms of volume.

Here's a breakdown:

* Sun's volume: 1.41 x 10^18 km³

* Jupiter's volume: 1.43 x 10^15 km³

Dividing the Sun's volume by Jupiter's volume gives you roughly 1000.

Keep in mind that this is a comparison of volume, which is a measure of three-dimensional space. If you're comparing their masses, the Sun is about 1,000 times more massive than Jupiter.
