A flyby mission has been proposed to Proxima Centauri b, an Earth-sized exoplanet in the habitable zone of its host star, Proxima Centauri, in the Alpha Centauri system. At a speed between 15% and 20% of the speed of light, it would take between 20 and 30 years to complete the journey, and approximately 4 years for a return message from the starship to Earth.
Breakthrough Starshot ... was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark Zuckerberg.
I should have expected this, but I didn't. He needs to step up his game compared to the other two I guess.
