Yuri Milner presented Breakthrough Starshot, a ground-based light beamer pushing nanocrafts, ultra-light space probes attached to lightsails, to speeds of up to 100 million miles an hour, which could reach Alpha Centauri in just over 20 years from launch. Together with Proxima Centauri (α Centauri C), Alpha Centauri A (α Centauri A) and Alpha Centauri B (α Centauri B) are considered a triple star system.
