Because Proxima Centauri is a red dwarf and a flare star, whether a planet orbiting it could support life is disputed.[31][32] Nevertheless, because of the star's proximity to Earth, it has been proposed as a flyby destination for interstellar travel,[33] which may include a fleet of interstellar StarChip spacecraft currently being developed by the Breakthrough Starshot project.[27]

I fully endorse R Price's suggestion: '' If we can speculate about physics, why not about education. Might the movie and the popular book be the basis of a general education science course? Imagine undergraduates arguing about the difference between wormholes and black holes. This may not be our current understanding of the laws of education, but it could happen. '''
Interstellar travel[edit]
Proxima Centauri has been suggested as a possible first destination for interstellar travel.[33] Proxima currently moves toward Earth at a rate of 22.4 km/s. Ηowever, after 26,700 years, when it will come as close as 3.11 light-years, it will begin to move farther away.[66]
If non-nuclear, conventional propulsion technologies are used, a flight of a spacecraft to a planet orbiting Proxima Centauri would probably require thousands of years.[88] For example, Voyager 1, which is now travelling 17.043 km/s (38,120 mph) relative to the Sun, would reach Proxima in 73,775 years, were the spacecraft traveling in the direction of that star. A slow-moving probe would have only several tens of thousands of years to catch Proxima Centauri near its closest approach, and could end up watching it recede into the distance.[89]
Nuclear pulse propulsion might enable such interstellar travel with a trip timescale of a century, beginning within the next century, inspiring several studies such as Project Orion, Project Daedalus, and Project Longshot.[89]
Project Breakthrough Starshot aims to reach the Alpha Centauri system with microprobes within twenty years, at twenty percent the speed of light, using around 100 GW of lasers.[90]
From Proxima Centauri, the Sun would appear as a bright 0.4-magnitude star in the constellation Cassiopeia.[91]
