Venus is the second planet from the Sun, and is Earth's closest neighbor in the solar system. Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a bright star in the morning or evening sky. The planet is slightly smaller than Earth, and its interior is similar to Earth. We can't see the surface of Venus from Earth, because it is covered with thick clouds that strongly reflect sunlight. However, space missions to Venus have shown us that its surface is covered with craters, over 1600 major volcanoes, mountains, large highland terrains, and vast lava plains. The surface of Venus is not where you'd like to be, with temperatures reaching more than 450C (approaching 900F - high enough to melt lead), an atmosphere 90 times heavier than our own, and clouds of sulfuric acid floating around to top it off!

Venus is one of the brightest objects in the sky, so it is clearly visible to the naked eye. It can be tricky to spot because it is always near the Sun. Because of this, it rises and sets with the Sun each day. Ancient civilizations believed they were actually two different objects, so they called the one which rose the Morning Star, and the one which sets the Evening Star. Of course, we now know it's the same object!

No one knows who really discovered Venus, since it is so obvious in the sky. However, much has been discovered about Venus in the past century. Robert Richardson noticed that Venus rotates "backwards". In other words, on Venus the Sun rises in the west and sets in the east.
