About the star :

A double star, pale white and purple, on the right arm of the Northern Twin (Castor). Wasat or Wesat from Arabic Wasat as-Sama', "Middle" of the sky. Or from Al Wasat, the Middle, i. e. of the constellation; but some have referred this to the position of the star very near to the ecliptic, the central circle. In China it was Ta Tsun, the Great Wine-jar. (Allen). The planet Pluto was discovered in this constellation on Feb 18 1930, close to this star.

Influence of the constellation:

"Ptolemy makes the following observations; the stars in the feet of Gemini have an influence similar to that of Mercury, and moderately to that of Venus; the bright stars in the thighs are like Saturn. It is said to cause trouble and disgrace, sickness, loss of fortune, affliction and danger to the knees. By the Cabalists it is associated with the Hebrew letter Qoph and the 19th Tarot Trump, The Sun". (Robson).

Remember, only the parallel and conjunction are important and the orb must be no more than 1 (one) degree.

Influence of the star:

Connected with chemicals, poisons and gas. Violence, malevolence, destructiveness as a first principal. (Robson).

Because of the Saturnine quality of this star, it gives a heaviness and tendency to pessimism. Apart from that however, Al Wasat does show up a quality of being able to speak with clear authority when others are waffling and prominence in public affairs or management is often the result.
