Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Delta Geminorum is a star in the constellation Gemini. It has the traditional name Wasat. The traditional name comes from the Arabic word for "middle". The star has an apparent magnitude of +3.5 and belongs to the spectral class F0. It is 59 light years distant. Wasat is only two-tenths of a degree south of the ecliptic, and therefore is occasionally occulted by the Moon and, more rarely, by a planet. The last occultation by a planet was by Saturn on June 30, 1857, and the next will be by Venus on August 12, 2420.
