The star Theta Serpentis (θ Serpentis) (whose A-component is otherwise known as Alya) is a binary star system composed of two bluish-white main sequence stars of spectral type A5.
Description (Specifications)[edit]
The θ1 and θ2 components of this star system lie approximately 900AU from one another, yielding a mutual orbital period of about 14000 years.
- A third G5 V star known to ancient Solomani astronomers as θ Serpentis C is merely a line-of-sight optical companion of the θ1/θ2 Serpentis system from the vantage point of a Terran-based observer, and is not actually a member of this star system.
History & Background (Dossier)[edit]
The Alya star system lies approximately 40pc from Terra, and is located in a Coreward/Corespinward direction from Terra at bearing 037.2o Galactic Longitude and +00.9o North Galactic Latitude.
