2.81
Hercules is large, but it doesn't contain any really bright stars. (The globular cluster called M13 is of interest.) These are the brightest stars (apparent magnitude) in Hercules: Kornephoros, Zeta Herculis, Sarin, Pi Herculis, Rasalgethi.
The surface temperature of Kornephoros (Beta Herculis) is approximately 8,390 degrees Celsius (15,134 degrees Fahrenheit). This star is a main sequence star located in the constellation Hercules, and it emits a white light.
The apparent visual magnitude of Beta Herculis is 2.81. It has been known since 1899 that it is in fact a binary star, and modern measurements (including satellite telescope) have resolved the motions and apparent sizes of the two bodies.
This star is also known as Beta Herculis, so it is obviously in constellation Hercules.
The brightest star in the constellation Hercules is Kornephoros, which has a white color.
The brightest star is Beta Hercules, or Kornephoros with magnitude 2.78. However, it is NOT the largest. Hercules contains several clusters, each with hundreds of thousands od stars, some of which may be larger. Furthermore, the constellation also contains the Hercules–Corona Borealis Great Wall, which is the largest known structure in the universe,
Some well-known stars in the constellation Hercules include Rasalgethi (Alpha Herculis), Kornephoros (Beta Herculis), and Sarin (Delta Herculis).
Magnitude means size. The magnitude of 8 is greater than the magnitude of 4. The magnitude of 1023209138109283 is greater than the magnitude of 12. =)) .... enjoyy... =D
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
The magnitude is '6' , because the numbers goes into the million, that is '10' to the power of '6'. 10^(6).
the brightness of a star is called it's magnitude
