Venus Visible at Sunset
The transit of the planet Venus took place today - for the last time in our lifetime. Venus is about the same size as Earth, and about 38 million km away from us, and about 100 million km from the sun. Today, we were able to see the planet silhouetted against the Sun, and at sunset, it could be seen with a 300mm lens. The next time this event will be visible is 2115!
