SOLAR SYSTEM

Detailed explanation-1: -Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Detailed explanation-2: -As a result, the planet’s early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. With no water left on the surface, carbon dioxide built up in the atmosphere, leading to a so-called runaway greenhouse effect that created present conditions.

Detailed explanation-3: -Overall, Earth, Mars, and Venus have similar atmospheres, interiors, surfaces, and similar greenhouse gases in the atmosphere. However, the different levels of greenhouse gases in the atmosphere change the temperatures of the planets quite significantly.

Detailed explanation-4: -Because of the cloud cover, the surface temperature of Venus would be a chilly-42C if were not for the greenhouse effect of its atmosphere. In reality, the surface of Venus, at 740K (467C) is even hotter than the surface of Mercury, which is a (relatively!) pleasant 440K.

Detailed explanation-5: -Venus is the hottest planet in our solar system, with a surface temperature of 869 degrees Fahrenheit, or 465 degrees Celsius.
