A school star, a star located 22 light years from the sun. This star has moved closer to the sun at a fairly close distance. In the study, it is said that 70,000 years ago, Schultz's star may have grazed the outer edge of the Auckland, which is at the edge of our solar system. The Schultz star may not be alone either, but it brings with it a companion, a brown dwarf. At that time, the sun and the star Schultz met at a distance of about 0.8 light years, or about 7.5 trillion kilometres. Although this distance seems far too us, on an astronomical scale, it is relatively close. It is the shortest distance from the sun before it finally moves away from the sun. At that close distance, it is likely that our ancestors who lived in the Northern Hemisphere will see the Schultz star with the naked eye as a point red pointed the sky.
