Star
The Sun has an apparent magnitude of −26.7, but its absolute magnitude is only +4.83. Sirius, the brightest star in the night sky as seen from Earth, is approximately 23 times more luminous than the Sun, while Canopus, the second brightest star in the night sky with an absolute magnitude of −5.53, is approximately 14,000 times more luminous than the Sun. Despite Canopus being vastly more luminous than Sirius, however, Sirius appears brighter than Canopus. This is because Sirius is merely 8.6 light-years from the Earth, while Canopus is much farther away at a distance of 310 light-years.
Gamma Scuti
Gamma Scuti, Latinized from γ Scuti, is a single, white-hued star in the southern constellation of Scutum. The apparent visual magnitude of 4.67 indicates this is a dim star but visible to the naked eye. Based upon an annual parallax shift of 10.21 mas as seen from Earth, this star is located about 319 light years from the Sun. Currently it is moving towards the Solar System at 41 km/s, which means in 2.35 million years it will pass at just distance, probably becoming the brightest star in the night sky, at magnitude −2.1, for a period.
