It has an absolute magnitude of -7.1 and an apparent magnitude of +0.12. It is over 900 light-years from Earth. SIRIUS Sirius (meaning "scorching" in Greek), also known as the dog star, is the brightest star in the sky (except for the sun). It is in the constellation Canis Major (The Great Dog).

A news frame natural disaster, but it was not until it became apparent that several thousands. Results: Here, we present ProQDock, a scoring function that predicts the absolute quality of docking model Therefore, it is highly important to establish reliable assumptions before inferring its magnitude.

By considering stars at a fixed distance, astronomers can compare the real (intrinsic) brightnesses of different stars. Vega was used as the reference star for the scale. Initially it had a magnitude of 0, but more precise instrumentation changed that to 0.3.

7) The star Capella has an absolute magnitude ('M') of -.48 and an apparent magnitude of .08. What is its luminosity and distance? Luminosity = n (4.83 -M) = n 5.31 = 133.05 = 133. distance = 10 (-.48 -.08 +5) ÷ 5 distance = 10 (4.44) ÷ 5 distance = 10 (.888) distance = 12.9 parsecs = 42.2 light years
