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.

Is the pressure on Venus high?
With a surface temperature of almost 480 °C (900 °C), this place is hot enough to melt lead. Because of Venus' heavy atmosphere, the planet's surface pressure is very high. Pressure is defined as the weight of the atmosphere pressing down on you per unit area. On Earth, we don't notice the air pressure at all.
Which planet has the highest pressure?
Surface Pressure of the Planets and the Sun
| Rank | Name | Surface Pressure (bar) |
|---|---|---|
| 1 | Saturn | >>1000 |
| 2 | Uranus | >>1000 |
| 3 | Neptune | >>1000 |
| 4 | Venus | 92 |
Why is Venus gravity so strong?
Since surface pressure is approximately the weight (mass times gravitational acceleration) of the atmosphere divided by the surface area, this means that surface pressure on Venus is very high compared to that of the Earth, by almost a factor of 100.
Can the pressure on Venus crush you?
In Venus's carbon-dioxide-rich atmosphere (deadly to humans), lightning storms are common, and fierce winds whip around the planet at high elevations. Gravity is about the same as on Earth, but atmospheric pressure on Venus is crushing: about 90 times that of Earth's.
What is Venus pressure?
The atmospheric pressure at the planet's surface varies with surface elevation; at the elevation of the planet's mean radius it is about 95 bars, or 95 times the atmospheric pressure at Earth's surface. This is the same pressure found at a depth of about 1 km (0.6 mile) in Earth's oceans.
What is the pressure on Venus compared to Earth?
There the similarities end. Venus has no surface water, a toxic, heavy atmosphere made up almost entirely of carbon dioxide with clouds of sulphuric acid and at the surface the atmospheric pressure is over 90 times that of the Earth at sea-level.
Why Venus is called Earth’s twin?
Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere. If the Sun were as tall as a typical front door, Earth and Venus would each be about the size of a nickel.
Has NASA landed on Venus?
Yes, several landers from the former Soviet Union have landed on Venus. They were only able to send us information for a short time because the extremely high temperature and pressure on the surface of Venus melted and crushed the landers.
How much does a 100 pound person weigh on Venus?
91 pounds The surface gravity on Venus is about 91% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 91 pounds on Venus.
