How many faint 6m stars can replace Venus (- 4m) in magnitude?
| August 3, 2020 | Education
The brightness difference between Venus and faint stars is 6m – (- 4m) = 10m.
Considering that a 5m brightness difference means a 100-fold change in the light flux, we see that it would take 100 x 100 = 10,000 faint stars to replace Venus alone.
