I know it roughly takes 20 minutes from Earth to Mars, and 8 minutes from the Sun to Earth, but don't know how long for the other planets on my list.
From Wikipedia, the mean Sun-planet distances are (in AU):
To get the maximum and minimum distances from Earth, add or subtract 1 AU. To get those distances in light-minutes, multiply by 8.317 light-minutes per AU. To save you the trouble:
These are maximuma and minima presuming circular orbits for all the planets. Calculating the distance the planets right now is more difficult but you can get the data from Solar System Live.
For the record, I've answered this question because it's really easy. But the OP should take note that an easy calculation with easily accessible data was all the he needed...
