Which constellation is the closest star to the earth observed at present?

At present, the closest stars to the Earth are located in proxima centauri Centauri and proxima centauri Centauri. There are countless stars in the vast space, among which the nearest star is proxima centauri, which is located in Alpha Centauri (scientific name is Alpha Centauri C), only 422 light years away from the sun, equivalent to 399.233 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.
