The Earth. The Earth's average surface temperature is about 60 degrees Fahrenheit or 15 degrees Celsius. Our atmospheric composition is about 78% nitrogen, 20-ish% oxygen, and then about less than 1% of a whole bunch of other gases. But Venus's atmosphere isn't like Earth's. We know that on Earth, carbon dioxide acts as a greenhouse gas.

Venus is the second planet from the Sun, and Earth's closest planetary neighbor. Venus is the third brightest object in the sky after the Sun and Moon. Venus spins slowly in the opposite direction from most planets. Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin.

It sits between the altitudes of 90-120 km, a region that is generally so cold at night that scientists often refer to it as Venus's cryosphere. The new measurements show that the temperature excess ranges from 30 to 70°C and peaks at an altitude of 100 km. This region of Venus's atmosphere contains light hazes of various aerosol

Venus's mean radius is 6,051.8 km (3,760.4 miles), or about 95 percent of Earth's at the Equator, while its mass is 4.87 × 10 24 kg, or 81.5 percent that of Earth. The similarities to Earth in size and mass produce a similarity in density—5.24 grams per cubic centimetre for Venus, compared with 5.52 for Earth.

The curious cold layer is far frostier than any part of Earth's atmosphere, for example, despite Venus being much closer to the Sun. The discovery was made by watching as light from the Sun filtered through the atmosphere to reveal the concentration of carbon dioxide gas molecules at various altitudes along the terminator - the dividing

Venus is the hottest planet in our solar system because it is covered by a thick layer of clouds composed of carbon dioxide and other gases, which prevent the heat from the sun from escaping back into outer space. This is why the planet continues absorbing the heat from the sun and becomes increasingly hot. Venus is the hottest planet in our

The atmosphere of Venus is the very dense layer of gasses surrounding the planet Venus.Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen, with other chemical compounds present only in trace amounts. It is much denser and hotter than that of Earth; the temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure

Venus is the closest planet to the Earth and the second closest planet to the sun. Although Venus is not the closest planet to the sun, it has the hottest surface temperature of any planet in the solar system, averaging at 842 degrees Fahrenheit (450 degrees Celsius).

https://physics.stackexchange.com/questions/25939/why-is-the-surface-of-venus-so-hot
1. Venus is really hot because of the CO2 in the atmosphere. The wavelengths that do reach Venus is enough for Venus to get hot. The 96% CO2 and its 90 times atmosphere means a lot of CO2 and this means even if 1% of solar radiation hits Venus it will heat up to the temperature it is now (452 degrees Celsius or roughly 900 degrees Fahrenheit).

https://coolcosmos.ipac.caltech.edu/ask/38-Why-is-Venus-so-hot-
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. Most of this heat cannot escape back into space because it is blocked by the very thick atmosphere of Venus.
