The brightest star is

The apparent brightness of a star is expressed by magnitude. The brightest star we see is generally rated as 1, and the darkest star that people with normal vision can barely see with the naked eye is rated as 6. 1850, the British astronomer Bergson formulated the standard. He measured the luminosity of stars with optical instruments, and determined that the brightness difference between each star is 2.5 12 times, so that the brightness of stars such as 1 is 100 times that of 6-star, while the brightness of stars brighter than the first star is 0 times. Brighter ones are represented by negative numbers, such as-1, -2, -3, etc. The following stars are 1 and brighter than 1: (the brightness ranking is in front of the number)-1 equal star (2 stars), and the English name belongs to the magnitude 1 Sirius-1.45 2 and Carina -0.73 0 equal star.
