The world needs a new source of energy, an unspillable source.

How long does it take to go to Jupiter from earth?

For example, how long would it take in a shuttle, assuming you were propelled along the way by an Ion engine?

If anyone needs to know the distance, assume 4.2 AU. At most it could be 6.2, but I’m assuming best-case-scenario.

If anyone could give me lowest and highest possible answers, that’d be great.
