- While Venus and Earth have similar sizes and are solar system neighbors, they have evolved very differently. Venus today lacks oceans, appears to lack plate tectonics, and has a massive carbon dioxide atmosphere that creates a greenhouse effect that makes the surface a hot hell.

Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.

In terms of their respective sizes, masses and compositions, Venus and Earth are quite similar. Whereas Earth has a mean radius of 6,371 km and a mass 5,972,370,000 quadrillion kg, Venus has a mean radius of about 6,052 km and a mass of 4,867,500,000 quadrillion kg. This means that Venus is roughly 0.9499 the size of Earth and 0.815 as massive. In ...
Being terrestrial planets, Venus and Earth have similar structures and compositions. Earth’s interioris divided into layers based on their chemical or physical properties, consisting of a core, mantle, and outer crust. Whereas the core region consists of nickel and iron, the mantle and outer crust are composed of silicate rock and minerals. While l...
Unlike other planet’s in our Solar System, the majority of Earth’s surface is covered in liquid water. In fact, about 70.8% of the surface is covered by oceans, lakes, rivers and other sources, with much of the continental shelf below sea level. In addition, Earth’s terrain varies greatly from place to place, regardless of whether or not it is abov...
Earth’s atmosphere is made up of five main layers – the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere. As a rule, air pressure and density decrease the higher one goes into the atmosphere and the farther one is from the surface. However, the relationship between temperature and altitude is more complicated, and ...
It is a well known fact that Earth’s strong magnetic field is intrinsic to it being able to support life. The main part of this field is generated in the core, the site of a dynamo process that converts the kinetic energy of convective fluid motion into electrical and magnetic field energy. The convection movements in the core are chaotic, causing ...
So let’s review. Earth and Venus have their share of similarities, but also some rather stark differences. Let’s compare them, category by category, placing Earth’s values on the left and Venus’ on the right.

The planet is nearly as big around as Earth – 7,521 miles (12,104 kilometers) across, versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon.
Nov 11, 2024 · The similarities to Earth in size and mass produce a similarity in density—5.24 grams per cubic centimetre for Venus, compared with 5.52 for Earth. They also result in a comparable surface gravity—humans standing on Venus would possess nearly 90 percent of their weight on Earth.

May 15, 2023 · Venus is two times more reflective than Earth because of the composition of its atmosphere. This is why from Earth, Venus is sometimes confused with a star and receives the nickname of the “morning star”. Unlike Earth, Venus doesn’t have the necessary conditions to have liquid water.
Feb 22, 2024 · Venus and Earth Size Comparison. Venus: Venus has a diameter of approximately 12,104 kilometers (7,521 miles), making it slightly smaller than Earth. Earth: With a diameter of around 12,742 kilometers (7,918 miles), Earth is slightly larger than Venus.
