is a
Triple Star System in the
Constellation Scorpius . It is approximately 459
Light Years from
Earth .
is a
Contact Binary of the
Beta Lyrae Type . Both its members are hot, blue-white
B-type Dwarf s. Together they have a mean
Apparent Magnitude of +2.89. Their rotation period is 1.57 days and they are separated by a distance of only 15
Solar Radii . Rotation causes their apparent magnitude to vary between +2.87 and +2.92.
They are orbited by a more distant companion designated , which has an apparent magnitude of +12.2. This distant companion is separated from the primary binary by 50
Arcseconds , putting it at least 7000
Astronomical Units away.
