Proxima Centauri
In the boundless space, there are countless stars, among which the nearest star is called proxima centauri, which is located in Alpha Centauri (scientific name: Alpha Centauri C), only 4.22 light years away from the sun, equivalent to 39,923.3 billion kilometers. If you travel to proxima centauri by the fastest spaceship, it will take 6.5438+0.7 million years for a round trip. It is conceivable that the universe is huge, even if it is close to you. Proxima centauri is a Samsung. They interact with each other, so in different historical periods, the "closest" crown of the world will be worn by these three stars in turn.
