Why does the encyclopedia say that the Pleiades cluster belongs to Taurus and the solar system is on Orion's spiral arm, but the solar system revolves around the Pleiades cluster? Ask an expert to explain. The Pleiades cluster is indeed near Taurus and much closer to our solar system than Orion, so it is not contradictory that the solar system revolves around the Pleiades cluster.

The reason why we are on the spiral arm of Orion is that the whole galaxy is a disk-shaped spiral galaxy, and many spiral arms extend from the center of the silver heart to the periphery, namely, the silver heart, the silver disk, the 2,000-second difference expansion ring, the 3,000-second difference arm, the rectangular inner arm, the centaur arm, the Sagittarius arm, the Orion arm, the Perseus arm and the Perseus outer arm. Our solar system, together with Taurus and Orion, is on the arm of Orion.
