Venus: A Day Longer Than a Year

One day on Venus lasts 243 Earth days because Venus spins backwards, with its sun rising in the west and setting in the east.

Traces of phosphine have been found in the atmosphere of Venus. It is a potential biomarker https://bit.ly/3wHXTWg

And the highest mountain on Venus, Maxwell Montes, is about 20,000 feet high (8.8 kilometers), similar to the highest mountain on Earth, Mount Everest.

There is no water on the planet, but it rains, entirely consisting of sulfuric acid. Still rain never reaches the planet's surface and evaporate from the heat, forming a phenomenon known as the virga.

And 1 more interesting fact about Venus is that it is often mistaken for a UFO. The planet is so bright that after sunset it can be observed even in gloomy weather. Venus appears in the sky before the stars, and passing clouds sometimes create the illusion of a bright cosmic body moving across the sky.
