The higher the magnitude, the dimmer the star appears to an observer on Earth. Therefore, the star with the lowest magnitude in the table would appear the brightest. In this case, that is a CMa with a visual magnitude of -1.46, making it the brightest star in the table. The magnitude of a star is a measure of its brightness, with smaller numbers indicating a brighter star. Among the choices in the table, a CMa has the smallest magnitude (-1.46), indicating it is the brightest star.
