List of brightest natural objects in the sky

This is a list of the brightest natural objects in the sky. This list orders objects by apparent magnitude from Earth, not anywhere else. This list is with reference to naked eye viewing; all objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly. Objects are listed by their proper names or their most commonly used stellar designation. This list does not include transient objects such as comets, man-made objects, or supernovae.

Notes

1. Maximum brightness derived from the average magnitude (−26.74^[1]), taking into account the Earth's orbital eccentricity (0.0167^[2]) as per the formula: ${\displaystyle -26.78\approx -2.5\log _{10}{\frac {10^{-26.74\cdot -0.4}}{(1-0.0167)^{2}}}}$
2. Average brightness derived from the magnitude of the average full moon (−12.74^[3]), assuming a quarter Moon is one-sixth as bright as the average full moon,^[4] as per the formula: ${\displaystyle -10.79\approx -2.5\log _{10}{\frac {10^{-12.74\cdot -0.4}}{6}}}$
3. Maximum brightness derived from the magnitude of the average full moon (−12.74^[3]), taking into account the Earth's orbital eccentricity (0.0167^[2]) and the Moon's orbital eccentricity (0.0554^[5]) as per the formula: ${\displaystyle -12.90\approx -2.5\log _{10}{\frac {10^{-12.74\cdot -0.4}}{(1-0.0167)^{2}\left(1-0.0554\right)^{2}}}}$
4. Combined magnitude derived from adding the magnitudes of Gamma² Velorum (1.83^[13]) and Gamma¹ Velorum (4.173 ± 0.009^[14]) as per the formula: ${\displaystyle 1.71\approx -2.5\log _{10}\left(10^{-0.4\cdot 1.83}+10^{-0.4\cdot 4.173}\right)}$
5. Combined magnitude from adding the magnitudes of Gamma² Velorum (1.81 maximum^[15]) and Gamma¹ Velorum (4.173 ± 0.009^[14]) as per the formula: ${\displaystyle 1.69\approx -2.5\log _{10}\left(10^{-0.4\cdot 1.81}+10^{-0.4\cdot 4.173}\right)}$
6. Combined magnitude derived from adding the magnitudes of Mizar A (2.220 ±0.003^[19]) and Mizar B (3.88^[20]) as per the formula: ${\displaystyle 2.01\approx -2.5\log _{10}\left(10^{-0.4\cdot 2.220}+10^{-0.4\cdot 3.88}\right)}$
7. Combined magnitude derived from adding the magnitudes of Alpha² Canum Venaticorum (2.88^[32]) and Alpha¹ Canum Venaticorum (5.60^[33]) as per the formula: ${\displaystyle 2.79\approx -2.5\log _{10}\left(10^{-0.4\cdot 2.88}+10^{-0.4\cdot 5.60}\right)}$
8. Combined magnitude derived from adding the magnitudes of Alpha² Canum Venaticorum (2.84 maximum^[34]) and Alpha¹ Canum Venaticorum (5.60^[33]) as per the formula: ${\displaystyle 2.76\approx -2.5\log _{10}\left(10^{-0.4\cdot 2.84}+10^{-0.4\cdot 5.60}\right)}$
9. Combined magnitude derived from adding the magnitudes of Beta¹ Capricorni (3.08^[37]) and Beta² Capricorni (6.10^[38]) as per the formula: ${\displaystyle 3.01\approx -2.5\log _{10}\left(10^{-0.4\cdot 3.08}+10^{-0.4\cdot 6.10}\right)}$
