How do you calculate the effective temperature of Venus?

Where a = albedo. Incorporating albedo we get the following estimates of effective temperature: Venus: 184 K. Earth: 255 K….If we treated real planets like idealized black-bodies, we get these effective temperature:

1. Venus: 327 K.
2. Earth: 279 K.
3. Mars: 225 K.

How much solar energy reaches each m2 at the top of Venus atmosphere on average?

However, these ideas seem to lack a heat transfer mechanism whereby the surface of Venus can radiate at 16,100 W/m².

Why is the temperature of Venus so high?

The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.

Does Venus have an extremely high pressure at its surface?

The atmospheric pressure at the surface of Venus is about 92 times that of the Earth, similar to the pressure found 900 m (3,000 ft) below the surface of the ocean. The pressure found on Venus’s surface is high enough that the carbon dioxide is technically no longer a gas, but a supercritical fluid.

How do you calculate the effective temperature of the earth?

By solving for TE in the preceding equation, we obtain TE = [S/4α × (1-A)]1/4. This is the effective radiating temperature of Earth. Using the known values of S of 1370 W/m2, A of 30\% or 0.30, and an α of 5.67 x 10-8 W/m2/K4, the Earth’s effective radiating temperature is calculated to be very cold, -18o C (255K).

Which planet has the highest effective temperature?

Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.

How much solar energy does Venus get?

The total solar flux at the Venus orbit is 2622 ± 6 W/m2 (Moroz et al., 1985). Due to its high albedo the planet absorbs only 157 ± 6 W/m2 on average, less than that deposited on Earth (~240 W/m2), despite the fact that Venus is 30\% closer to the Sun.

How much sunlight reaches the surface of Venus?

An inhospitable surface lies beneath Venus’ thick cloud cover. Credits: ESA/C. Carreau. On Venus, only ten percent of the incoming solar radiation reaches the surface; most of it is reflected back into space by the planet’s dense cloud cover, making Venus appear to shine brightly in the night sky.

What makes Earth similar with Venus?

Venus is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. Venus also rotates backwards compared to Earth and the other planets.

How hot is Venus compared to Earth?

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. In fact, at a searing 750 K (477 °C), the surface of Venus is the hottest in the solar system.
