On Venus, the Sun rises in the west.
Venus spins backwards — opposite to its orbit and to nearly every other planet in the Solar System. Stand on its surface and the Sun would rise in the west, and the best explanations we have are a giant early impact or the slow torque of its own enormous atmosphere.
Step by step
- Nearly every planet spins the same direction it orbits. Venus does the opposite.
- From its surface, the Sun would rise in the west and creep east across the sky.
- Prime suspects: a colossal early impact, or the slow torque of its massive atmosphere.

Space facts are where the numbers stop making sense. A total eclipse only works because the Sun is 400 times wider than the Moon and 400 times further away. Venus spins backwards, some of the static on an old TV was the Big Bang, and almost all of the universe is missing. Every fact here links to its source.
