If nothing else, the possibility of
sending light sails to orbit many nearby stars suggests a natural next - generation, longer - term follow - up to Starshot's more urgent mission goals.
To reach the potentially habitable planet Proxima b, these «photogravitational» assists counterintuitively require first
sending the light sail swooping blisteringly close to the bright, sunlike stars Alpha Centauri A and B — even though they are nearly two trillion kilometers farther from us than Proxima b's smaller, dimmer host star, Proxima Centauri.

Rather than using multibillion - dollar laser arrays to boost small
