Planet Venus is illuminated by the Sun about twice as strong as planet Earth, but due to the high albedo of the cloud cover
Planet Venus is illuminated by the Sun about twice as strong as planet Earth, but due to the high albedo of the cloud cover, a significant part of the incident solar radiation is reflected from the clouds in its atmosphere. As a result, the surfaces of Venus and the Earth receive approximately the same amount of light energy. Why is Venus so much hotter than Earth? {Note. Albedo (from Latin albus – light) – a value that characterizes the reflectivity of a surface; expressed as the ratio of the energy of radiation reflected by the surface to the energy of solar radiation falling on the surface.)
This is due to the fact that the atmosphere of Venus is almost entirely composed of gases that create a strong greenhouse effect. Because of this, there is a significant increase in temperature on the surface of Venus.
