What is the name of the brightest star in the sky?

The apparent brightness of a star is expressed by magnitude. The brightest star we see is generally defined as 1, and the darkest star that a person with normal vision can barely see with the naked eye is defined as 6. 1958+0850, the British astronomer Pogson set the standard. He measured the luminosity of stars with optical instruments and determined that the brightness difference between each magnitude was 2.565438+. Brighter ones are represented by negative numbers, such as-1, -2, -3, etc. The following stars are 1 and the brightness is greater than 1: (the brightness ranking is before the number)-1, etc. (2 stars) English names belong to the constellation magnitude 1 Sirius Laoge-1.45 2 Laoge-0, etc. Ken Taurus Centauri-0.104 arcturus Sagittarius -0.06 5 Vega Lyra 0.04 6 Capella 0.08 7 Betelgeuse Orion Betelgeuse 0.10.8 South River Three South River Three 0.35. 9 Water Resources Commission-Archer Napo constellation 0.46 1 equal star (12 star) 10 Betelgeuse Orion 0.801kloc-0/horse belly-Hadar Centauri 0.6012 Hegu ErAltair Eagle.
