Venus is the second-closest planet to the Sun, orbiting it every 224.7 Earth days. It is sometimes called Earth's "sister planet", for the two are similar in size, gravity, and bulk composition. Venus is named after the Roman goddess of love and beauty.
When humans first explored space in the mid 20th century, they found Venus to be world with too much atmosphere, the greenhouse effect run wild, and no chance for life. It did not at all resemble the romantic version dreamed up by pre-alien contactscience fiction writers such as Stanley Weinbaum.
