Type of Planet
Venus is a terrestrial planet, meaning primarily composed of rock and metal.
It has many similarities to Earth, including; components, size, mass, density, and distance to the Sun, which have earned Venus a nickname of Earth's "sister planet".
Venus is made up of an iron core and a rocky mantle, similar to the composition of the Earth.
Size (Diameter), Mass, and Density
Venus is a similar size and mass to Earth. It is 95 percent the diameter of the Earth and 80 percent of the Earth's mass.
The density of Venus is 5.24 grams per cubic centimeter, compared to Earth's 5.51.
As Venus is a similar size, mass, and density, to the Earth, it also has a similar gravity. Venus has 91 percent of the Earth's gravity.
Venus is a rarity among planets, it does not internally generate a magnetic field.
Venus differs radically from Earth because of its dense, 96 percent, carbon dioxide atmosphere. Venus' cloudy atmosphere traps much of the Sun's heat, and makes the planet far too hot for life.
Its highly reflective acidic atmosphere, also makes Venus the brightest of all the planets visible from Earth.
Venus is the hottest planet in the solar system. The average temperature on Venus is 462 degrees celsius. Lead would melt on the surface.
Length of a Day (Rotation)
Venus rotates on its axis very slowly. A day on Venus lasts 243 Earth days.
Venus has a very small axial tilt of 3 degrees, versus Earth's 23.5 degrees. Venus also has a smaller orbit than Earth, which makes its seasons shorter, and variations in temperature and conditions extremely slight.
Length of a Year (Orbit)
Venus orbits the sun quicker than Earth, so a year on Venus lasts only 225 Earth days. As a day on Venus lasts 243 Earth days, a day on Venus lasts longer than a year.
Distance from the Sun
Venus is the second planet from the Sun at 67 million miles.
