* Distance isn't consistent: The planets' orbits are elliptical, meaning their distance from the sun changes throughout their orbit.

* No planet is *exactly* twice as far: There's no planet that's precisely twice the distance from the sun as Jupiter.

However, we can find a planet that's *approximately* twice as far as Jupiter:

* Saturn is roughly twice as far from the sun as Jupiter. It's an average of 9.5 AU (astronomical units) from the sun, while Jupiter averages 5.2 AU.

So, while not perfect, Saturn is the closest answer to the question.
