What is the quantified albedo value representing Venus's reflectivity of sunlight?
Answer
0.7
Albedo is the term used to quantify the reflectivity of a celestial body, indicating the percentage of incident sunlight that is reflected back into space. Venus boasts a very high albedo value of 0.7. This means that, on average, 70% of the sunlight that strikes the planet's cloud tops is immediately reflected away, contributing significantly to how bright it appears to an observer on Earth, even though Mercury might possess a higher albedo depending on the measurement system used.
