Adhara comes from the Arabic phrase “Al Adhara”, and roughly translates as “girls”. This is a binary star system consisting of Epsilon Canis Majoris A and the accompanying star Epsilon Canis Majoris B. Here I am writing about the star Epsilon Canis Majoris A. Adhara is the second brightest star in the constellation Canis Majoris and is 430 light-years from Earth. Of course, the brightest star in the constellation Canis Majoris is Sirius. Adhara forms a recognizable constellation shape in the sky. It is a beautiful star that with a magnitude of 1.5 is not difficult to find in the night sky. Approximately 4.7 million years ago, Adhara was only 34 light-years from Earth and with a magnitude of -3.99 was the brightest star in the sky.
Adhara the brightest star
When you look at Canis Majoris, you will see that Adhara together with Sirius and the Furud star form a recognizable triangle. Star is right down below Sirius, and in a way remains in the “shadow” of the majestic Sirius. The surface temperature of the Adhara star is estimated at approximately 23,000 K, and it is much higher than our Sun. In addition, Adhara is the brightest ultraviolet object in the night sky. With total data, Adhara is 38,600 times brighter than the Sun. However, all this is not just in the visible spectrum. Due to the high temperature of the star, a good part of its energy Adhara reflects in the invisible ultraviolet spectrum. And the question arises, is Adhara in the “shadow” of Sirius. If you saw this star with ultraviolet eyes, Adhara would be the brightest star in the sky. An interesting and bright star.
