Allowing that the speed of light is 186,000 mps, then:
- Mercury (36) = 3 1/2 minutes
- Venus (67.2) = 6 minutes
- Earth (93) = 8 1/2 minutes
- Mars (141.7) = 13 minutes
- Jupiter (484) = 43 minutes
- Saturn (887) = 1 hour, 19 minutes
- Uranus (1785) = 2 hours
- Neptune (2795)= 4 hours, 10 minutes
- Pluto (3675) = 6 1/2 hours
