## Definitions
1. The second brightest star in the constellation of Centaurus, Beta Centauri

## Etymology
From Arabic حضار.
In Star-Names and Their Meanings, Richard Hinckley Allen writes,
"Ḥḍar and Wazn, Ground and Weight, seem to have been applied without much definiteness to α and β of this constellation, and to stars in Argo, Columba, and Canis Major, probably on account of their proximity to the horizon; the meridian altitude of β, 1000 years ago at Cairo, is 30° of north latitude, being only 4°. Hyde, however, said that α and γ were the stars referred to by these Arabic titles."
However, the word حضار does not normally mean "ground" but settled land.
