By my napkin math, from 32 billion km away, a 2deg error means Voyager 2 is pointing to a spot 1.12 billion km away from Earth (at right angles). That’s roughly the distance from Earth to Saturn 😅

Turns out there’s only about 0.25 kW of energy in a lightning bolt - which costs maybe 5-10 cents in the US - so it’s not really worth it.
