- lukan 2y agoNo, Voyager uses a radioactive battery. The sun is already way too far away for Voyager, to provide enough energy.
- thinkcontext 2y agoVoyager doesn't use solar power since its incredibly faint as you get further from the Sun. It uses the heat from the decay of radioactive plutonium to generate electricity.
