What kind of star is Zubenelgenubi?
What is the apparent magnitude of Zubenelgenubi?
Zubenelgenubi has an apparent magnitude of 5.15, this is a measure of the brightness of the star as seen from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of 3.28 If you used the 2007 Parallax value, you would get an absolute magnitude of 3.34.
How old is the star Zubenelgenubi in years?
The star can be seen with the naked eye, that is, you don’t need a telescope/binoculars to see it. The star has an estimated age of 1.10 Billion of Years but could be as young as 0.30 to 1.70 according to Hipparcos. Zubenelgenubi is a Binary or Multiple star system.
What is the brightness of the star Zubeneschamali?
Zubeneschamali is a suspected variable, showing brightness variations with an amplitude of 0.3 magnitudes. It has been suggested that the variations are caused by the presence of a smaller companion, but one has never been detected around the star and, for this reason, Beta Librae is classified as a single star.
What is the absolute magnitude of a star?
Absolute Magnitude is the apparent magnitude of the star from a distance of 10 parsecs or 32.6 light years. This assumes that there is nothing in between the object and the viewer such as dust clouds. To really compare the brightness of the star, it is best to use Absolute rather than Apparent Magnitude.
