Detailed explanation-1: -Surface temperatures on Venus are about 900 degrees Fahrenheit (475 degrees Celsius) – hot enough to melt lead.
Detailed explanation-2: -However, for all the characteristics these two planets have in common, average temperature is not one of them. Whereas the Earth has an average surface temperature of 14 degrees Celsius, the average temperature of Venus is 460 degrees Celsius. That is roughly 410 degrees hotter than the hottest deserts on our planet.
Detailed explanation-3: -Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that we see firsthand on Earth with global warming. As a result, temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is more than hot enough to melt lead.
Detailed explanation-4: -There the temperature varies considerably, reaching a maximum of about 300–310 kelvins (K; 80–98 °F, 27–37 °C) in the daytime and dropping to a minimum of 100–130 K (−280 to −226 °F, −173 to −143 °C) at night.
Detailed explanation-5: -Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus.
