Adhara

Adhara is the traditional name of the binary star system Epsilon Canis Majoris, the second-brightest star in the constellation Canis Major after Sirius. The name derives from the Arabic word عذارى (ʿadhārā), meaning "maidens" or "virgins." This star has been known since antiquity and was historically significant: about 4.7 million years ago, it was the brightest star in the night sky, with an apparent magnitude of −3.99. Today, it ranks as the 22nd-brightest star overall, with an apparent magnitude of 1.50, and lies approximately 405–428 light-years from Earth based on Hipparcos and Gaia mission data.

Etymology and Cultural Context

The Arabic root ʿadhārā is also the source of the related name Azra (Urdu), which shares the meaning "maiden." In Arabic astronomy, the star was part of a group of stars associated with maidens, reflecting a common theme in celestial naming. The name Adhara is sometimes used as a feminine given name, inspired by the star's beauty and brightness.

Notable Bearers

While Adhara is primarily known as a star name, it has been adopted as a personal name in modern times, particularly in English-speaking countries, as part of the trend of using astronomical names for girls. Notable individuals with the name include Adhara Pérez, a Mexican child prodigy with an IQ higher than Albert Einstein and Stephen Hawking, who gained international attention for her achievements in mathematics and science.

Related Names

A variant of Adhara is Aludra, another star name in Canis Major (Eta Canis Majoris), which also derives from the same Arabic root. The Urdu name Azra is a cognate, meaning "maiden."
