Where 779 fits
Why 779 is special
At that distance sunlight is about four percent as intense as at Earth, which is why missions to Jupiter historically used nuclear power sources. Juno's large solar arrays were a deliberate demonstration that solar power could work that far out.

Saturn is roughly twice Jupiter's distance. A radio command takes about 80 minutes to reach it, which is why spacecraft there must act on stored instructions.

Sunlight at Jupiter is about a twenty-fifth as strong as at Earth, which long made solar power impractical for outer-planet missions. Juno reached Jupiter on solar arrays in 2016, which was a demonstration as much as an engineering choice.
