Which constellation is closest to the sun?

At present, the nearest star to the Earth is located in Centauri, which is called proxima centauri.

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.
