1. It spins backwards!
All other planets spin anti-clockwise on their axis and orbit the Sun in an anti-clockwise direction. Venus also orbits the Sun anti-clockwise, but its unusual axis rotation is due to being upside down - it was knocked off its upright position earlier in its history! Astronomers believe that at some point, a colliding celestial body tilted Venus so far off its original position that it is now upside down. The only other planet to spin in a weird direction is Uranus which spins on its side, probably the result of another collision early on in its life.
2. 1 Venusian day is longer than a Venusian year!
It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun. That’s 243 Earth days to rotate once and only 224.7 Earth days to complete one orbit of the Sun.
3. Venus is also called "Earth's sister planet"
4. It is the hottest planet in the Solar System!
The average surface temperature is 462 °C, and because Venus does not tilt on its axis, there is no seasonal variation. The dense atmosphere of around 96.5 percent of carbon dioxide traps heat and causes a greenhouse effect.
