Subaru is the Pleiades star cluster visible in the Taurus constellation.
"Subaru" means "united" in Japanese. It is the Japanese name for the blue-colored Pleiades (also called M45) open star cluster. The Pleiades contain mostly young and hot blue stars that are only about 100 million years old. They illuminate the gas within the cluster. Located in Taurus, the bull, Pleiades is one of the nearest star clusters to Earth. It can be seen as a fuzzy little cloud with the naked eye, northwest of the constellation’s main star Aldebaran, the orange eye of the bull. The Pleiades, sometimes also called the “Seven Sisters”, have had meanings in different cultures and traditions for thousands of years.
