what is the temperature range of venus compared to earth?
606927
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.

The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet. The atmosphere traps the small amount of energy from the sun that does reach the surface along with the heat the planet itself releases.

Average Temperature on Each Planet Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system's hottest planet.

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.

There are the inner, rocky terrestrial planets and then the outer gas giants. Venus is a terrestrial planet. ... The main difference between Earth and Venus is the incredibly thick carbon dioxide atmosphere, which raises temperatures on the surface of Venus to the point that it's hot enough to melt lead.

The principal difference between the two planets is the lack of evidence for plate tectonics on Venus, possibly because its crust is too strong to subduct without water to make it less viscous. This results in reduced heat loss from the planet, preventing it from cooling.

Mars and Venus. Mars and Venus are the two terrestrial planets most similar to Earth. One orbits closer to the Sun, and one orbits more distant to the Sun. But both are visible with the unaided eye, and two of the brightest objects in the night sky.

By size, Venus and Earth could be twins. Venus is less than 1000 km thinner while Mars is only 38% the size of Earth. All three have an atmosphere. ... The atmospheric pressure is intense on Venus at 90 Earth atmospheres, normal on Earth [of course] at one atmosphere and only about 0.6% of Earth's pressure on Mars.

Size, Mass and Orbit: Whereas Earth has a mean radius of 6,371 km and a mass 5,972,370,000 quadrillion kg, Venus has a mean radius of about 6,052 km and a mass of 4,867,500,000 quadrillion kg. This means that Venus is roughly 0.9499 the size of Earth and 0.815 as massive.

Because Venus was slightly closer to the Sun than the Earth, its water never liquified and remained in the atmosphere to start the greenhouse heating. As Venus heated up, some of the carbon dioxide in the rocks was "baked out." The increase of atmospheric carbon dioxide enhanced the greenhouse heating.

Light from the Sun strikes the ground of Venus, and warms it up. The ground tries to radiate heat back into space but the carbon dioxide traps much of it around the planet keeping it so warm. ... Water vapor is an even more powerful greenhouse gas than carbon dioxide and this caused temperatures to rise even more.

The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere.
469687
Because Venus has such a dense atmosphere which is some 100 times thicker than the earth's. Evidently, Venus is sufficiently close to the Sun that the little carbon dioxide it had in its early, Earth-like atmosphere caused the surface to warm up and leach out more carbon dioxide into the atmosphere.

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 × 1024 kg, or 81.5 percent that of Earth.

Atmosphere. Venus' atmosphere consists mainly of carbon dioxide, with clouds of sulfuric acid droplets. The thick atmosphere traps the Sun's heat, resulting in surface temperatures higher than 880 degrees Fahrenheit (470 degrees Celsius).

The atmosphere of Venus is very hot and thick. ... The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet. The atmosphere traps the small amount of energy from the sun that does reach the surface along with the heat the planet itself releases.
