Venus


Venus is the second planet from the Sun. About the same size as Earth, Venus is sometimes called our sister planet. But these sisters couldn’t be more different. Named after the Roman goddess of love, Venus is probably the nastiest place in the Solar System. If anyone landing on it could resist the heat, they would be suffocated by unbreathable carbon dioxide, burned by sulphuric acid and crushed by air pressure about 90 times that on Earth.

Day and year

Venus spins slowly on its axis (and backwards, the only planet except for Uranus to do so). It actually takes longer to complete one rotation than it does to orbit the Sun. So Venus’s day is longer than its year.

Clouds

Venus is permanently covered in thick clouds. These are made not of water, but droplets of deadly sulphuric acid. Because its cloud cover reflects the light of the Sun from its surface, Venus is a very bright object in the night sky, the brightest after the Moon.

Volcanoes

There are many thousands of volcanoes on Venus. Most of the planet’s surface is made up of plains of lava, molten rock from inside the planet that has erupted through volcanoes. Lava flows have cut channels in the ground that look quite similar to river channels. Smaller, dome-shaped volcanoes, known as “pancakes”, can also be found on Venus. These are formed when lava slowly oozes to the surface and cools.

High temperatures

Venus is the hottest world in the Solar System. Its dense atmosphere (the blanket of gases that surrounds it) prevents heat from escaping. The temperature on Venus is always about the same: 490°C (910°F). This is hot enough to melt lead.
