Pleione is a star located in the constellation of Perseus. It is part of the Pleiades star cluster, which is also known as the Seven Sisters. Pleione is classified as a B-type main-sequence star, meaning it is relatively hot and bright compared to other stars. It has a surface temperature of about 12,000 Kelvin and is approximately 367 light-years away from Earth. Pleione is notable for its variability; it is classified as a Be star, which means it exhibits changes in brightness due to the presence of a disk of gas around it. This disk can emit light and cause the star to appear brighter at times. The Pleiades cluster, which includes Pleione, is one of the nearest star clusters to Earth and has been a significant point of interest in astronomy for centuries.
