Key Facts

Main Gas
Mostly carbon dioxide. It makes up 96.5% of the atmosphere.
Surface Temperature
About 467 degrees Celsius (872 degrees Fahrenheit). Hot enough to melt lead.
Surface Pressure
About 93 times Earth's air pressure. Like being 900 meters underwater.
Cloudy Cover
The planet is completely covered by thick clouds of sulfuric acid.

Venus's Super-Thick Blanket!

Venus is like a planet wearing a giant, puffy coat made of gas! This coat is called its atmosphere. It's way thicker and hotter than Earth's.

The air is so squished, it feels like being deep underwater. And guess what? It's covered in clouds, but not the fluffy white kind.

These clouds are made of yucky sulfuric acid, like in car batteries! They hide the planet's surface from view, making Venus a mystery planet.

A Speedy Spin Cycle!

Even though Venus spins super slowly, its atmosphere zooms around the planet incredibly fast! It's like a race car going around a track. The winds at the top of Venus's atmosphere can blow faster than a speeding train, circling the whole planet in just four Earth days.

That's way faster than Venus itself spins! Down near the ground, though, the winds are much calmer, like a gentle breeze on a playground.

Hot, Hot, Hot!

The air on Venus is so hot, it's hotter than your oven when it's baking cookies! The temperature is hot enough to melt lead. This is because Venus has a lot of carbon dioxide gas, which traps heat like a greenhouse.

It's like leaving a car parked in the sun with all the windows rolled up. This makes Venus the hottest planet in our solar system, even hotter than Mercury, which is closer to the Sun!

What's Hiding Up High?

Even though the ground on Venus is super hot and squished, there's a special place high up in its atmosphere that's surprisingly like Earth! Around 50 to 65 kilometers (about 30 to 40 miles) up, the air pressure and temperature are almost the same as here on Earth. It's so similar that scientists have even thought about building floating cities there, like giant balloons in the sky!
