Brightest Stars
The brightest stars in Earth's night sky, ranked by apparent magnitude. Lower magnitude = brighter. The Sun has an apparent magnitude of -26.74; the faintest stars visible to the naked eye are around magnitude 6.
About Apparent Magnitude
Apparent magnitude measures how bright a star appears from Earth. The scale is logarithmic and inverted: lower values mean brighter objects. Each step of 1 magnitude represents a brightness factor of about 2.512. A magnitude 1 star is exactly 100 times brighter than a magnitude 6 star. Negative magnitudes indicate extremely bright objects — Sirius shines at -1.46, making it the brightest star in Earth's night sky.
