Answer:
There are currently no answers to this question based on planets, only stars, but I can do for you that Venus is the second-brightest object in our sky, but just with a luminosity magnitude of -4.6, brighter than the Sirius. So, although both are non-luminous, it is a hypothesis that says that Venus (based on my calculation) is 41.805306 L. Since Earth is non-luminous and we are living in it, Venus is 41.805306 times as luminous as Earth
Step-by-step explanation:
How to calculate the luminosity.
[luminosity = brightness x 12.57 x
