How many light minutes is it from Jupiter to Earth?

That depends on how far apart Jupiter and earth are at the time.

When both are on the same side of the sun, the closest the two planets can be

from each other is about 391 million miles. When on opposite sides of the sun,

the farthest apart is about 577 million miles.

The corresponding transit-times at light speed are between 35 minutes and 51.6 minutes.
