the question is:
"The absolute magnitude of a star is -12.. How would you describe its brightness?"
Its brightness (or apparent magnitude) will also depend upon how far away it is. If it is 10 parsecs (3 light years) away, it will be about as bright as a full moon as seen from Earth. The star's absolute magnitude is 14.7 magnitudes brighter than the sun. That is about million times brighter, when seen from the same distance.
