ARICNS = 00916Beta Virginis (β Vir / β Virginis) is a
star in theconstellation Virgo. It also has the traditional names Zavijava (also Zavijah) and Alaraph [Atlas of the Heavens, part II, catalogue, Antonín Bečvář] . Despite being the "beta" star of the constellation Virgo it is only the fifth star in order of brightness.Physically, Beta Virginis is larger and more massive than the Sun, and is comparatively metal-rich. That is, it has a higher preponderance of elements heavier than helium.
Since it is close to the
ecliptic , it can be occulted by theMoon and (very rarely) byplanet s. The next planetaryoccultation of Zavijava will take place on11 August 2069 by Venus.This was the star Einstein used during the solar eclipse of September 21, 1922 to determine the speed of light in space, as it fell close to the Sun.
Etymology
The medieval name Zavijava (Zavijah, Zavyava, Zawijah) is from the Arabic زاوية العوى "zāwiyat al-cawwa’" "Corner of the barking (dog)". Another name was Alaraph.
