Venus, which is the second planet from the sun, is named after the Roman Goddess of love and beauty.
Venus comes at rank 6 in terms of size and mass in the solar system.
Venus is often called "Earth’s twin" because they’re similar in size and structure.
Longer day shorter year:
As Venus rotates very slowly on its axis its one day on Venus lasts 243 Earth days. However the planet orbits the Sun faster than Earth, thus one year on Venus takes only about 225 Earth days.
Venus’ is the hottest planet in our solar system due to its thick atmosphere that traps heat creating a runaway greenhouse effect.
Venus and Uranus are the only planets that rotate backward at their axis which means Sun rises at this planet in the West and sets in the East.
