Venus is often named as Earth's twin because both worlds share a similar size, surface composition and have an atmosphere with a complex weather system. Whereas Earth rotates in about 24 hours Venus rotates in the contrary sense (retrograde rotation) in 243 days. ...

How are Venus and Earth different?
Venus is similar in size to Earth. Earth is just a little bit bigger. Venus is unusual because it spins the opposite direction of Earth and most other planets. And its rotation is very slow.
What does Earth and Venus have in common?
Venus, Mars and Earth, three out of the four inner or 'rocky' planets of the Solar System, have a lot in common – a solid surface you could walk on, a comparable surface composition, an atmosphere and a weather system.
Why are Venus and Earth atmospheres so different?
While Venus' atmosphere is mostly carbon dioxide, it is much thicker than Earth's, and contains four times the nitrogen. Even with it's vast oceans, Earth's atmosphere would likely have been dominated by carbon dioxide were it not for the appearance of life.
Why is Venus called Earth's sister?
Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
What are the difference and similarities of Venus Earth and Mars?
Mars is much smaller, with a diameter of only 6,792 km. And again, in terms of mass, Venus is almost Earth's twin. It has 81% the mass of Earth, while Mars only has 10% the mass of Earth. The climates of Mars and Venus are very different, and very different from Earth as well.
Is Venus older than Earth?
Whereas Earth's oceanic crust is continually recycled by subduction at the boundaries of tectonic plates, and has an average age of about 100 million years, Venus' surface is estimated to be 300–600 million years old.
Does Earth and Venus have the same orbit?
Because Venus's orbit is nearer the Sun than Earth's, the planet is always roughly in the same direction in the sky as the Sun and can be seen only in the hours near sunrise or sunset. When it is visible, it is the most brilliant planet in the sky. Venus is designated by the symbol ♀.
