101 Facts About the Planet Venus


Venus is the second planet from the Sun and the second-largest terrestrial planet in our solar system. It’s also the third brightest object in our planet’s sky next to the Sun and Moon. Want to know more crazy facts? Keep on reading to learn 101 facts about the planet Venus.               

Fact 1: The thick Sulfuric Acid clouds that envelopes Venus’ prevent its surface from being seen from space in visible light.

Fact 2: The average temperature on Venus, 462°C, is easily hot enough to melt the metal Lead, which has a melting point of 327.5 °C.

Fact 3: 85% of all the craters on Venus are perfectly preserved. This indicates that instead of constant technic activity slowly destroying and renewing the crust, the planet experiences a catastrophic global resurfacing event about 450 million years due to a build-up heat in the mantle.

Fact 4: The density of Venus’ atmosphere at the surface is 0.065 g/cm3. That’s 6.5% the density of water!

Fact 5: The planet Venus is named after the Roman goddess of love and beauty.
