One day on Venus is longer than 116 days on Earth. Venus and Earth are often called twins because they are similar in size, mass, density, composition, and gravity. Venus is about 38 million kilometers away from Earth (2361210.531 miles). Billions of years ago Venus actually looked like Earth and the climate was very similar. Venus is only a little bit smaller than Earth, but looks similar on the inside. The atmospheric pressure of Venus is 92 times stronger than Earth’s. Earths atmosphere pressure is about 14.7 pounds per square inch. Venus is also the second closest planet to the sun and the closest to the Earth. The mass of Earth is about 1.23 times the mass of Venus. Venus has a weak magnetic field mostly because Venus has a lot more atmosphere than earth.
