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.
