*Negative magnitudes are brightest, and one magnitude difference corresponds to a difference in brightness of 2.5 times; e.g., a star of magnitude –1 is 10 times brighter than one of magnitude 1.5.
**One light-year equals about 9.46 trillion km.
***A and B are brighter and fainter components, respectively, of star.
