The Similarity of Venus to Earth – Science Game

This science game helps children in discovering more about the planet Venus. Venus, the second planet from the Sun, is the brightest natural object in Earth's night sky. It can cast shadows, and its surface can be seen with the naked eye in daylight. Read on to learn more about Venus's similarity to Earth. And remember, we are not alone in our confusion. Venus is a beautiful planet! It is definitely worth exploring and learning more about. There is even a lot of planetary science to learn about Venus.

Earth's twin planet
It's no surprise that scientists have dubbed Venus as Earth's twin planet. Venus is similar to Earth in mass, size, and density. They likely formed from the same rocky building blocks, and their chemical compositions are similar as well. However, early telescopic observations of Venus suggested it was a warm, wet world. This theory was disproved by modern scientific observations, however, and scientists now know that Venus and Earth have evolved very different surface conditions.
Similarity to Earth in structure
The similarity to Earth in structure can be traced to the similarities of its inner and outer cores. Like Earth, Venus has an iron core, a hot-rock mantle, and an outer rocky crust. Its core is partially liquid and is cooling at the same rate as Earth's. This similarity between the two planets has led scientists to conclude that Venus's structure is very similar to Earth's.
Similarity to Earth in rotation
While both planets revolve around the Sun, Venus is far closer to the Sun than Earth. Venus's average temperature is more than 460 degrees Celsius, while Earth's is only 14 degrees. Venus is the third planet from the sun, and the fifth largest non-gas planet in our solar system. The similarities between Earth and Venus begin with its ionosphere. These ionospheres are composed of gases that are electrically excited by the Sun's ultraviolet rays. This plasma, called the solar wind, carries the magnetic field of Venus.
Similarity to Earth in atmosphere
The similarities between Earth and Venus extend beyond its atmosphere. Both are rocky planets and share many of the same physical and chemical properties. In fact, Earth and Venus have similar internal structures, and their cores are made of the same minerals and elements. They have a similar radius, mass, and density, and their atmospheres are almost identical. Venus also lacks plate tectonics, so there is no evidence of them.
Similarity to Earth in size
In terms of size, Venus is similar to Earth. It is a rocky body similar in size and mass, making it a good candidate for the nickname "Earth's twin". Venus' diameter is approximately twelve thousand miles (7,520.8 km) and its mass is 81 percent that of Earth. However, Venus is quite different on the surface, with the difference being greatest in its atmosphere. In fact, the atmosphere of Venus is almost entirely carbon dioxide and nitrogen.
Similarity to Earth in volcanoes
Scientists have confirmed that the volcanic landscape of Venus resembles that of Earth. They have observed that 80 percent of Venus is covered in volcanic features and the basaltic ocean floor is similar to that of Earth. However, volcanism on Venus is believed to have occurred in a different way. Moreover, Venus' volcanoes are impressive in size, with a field of up to 7,000 shield volcanoes measuring up to 1000 kilometers in diameter. While this is huge, the size of the Earth's Mauna Loa is only 120 kilometers across.
Similarity to Earth in surface temperature
Venus' surface temperature is similar to Earth's, but the differences aren't as drastic. The highest mountain on Venus, Maxwell Montes, is 11 km high. Venus has a southern continent named Aphrodite Terra after the Greek goddess of love. This continent is roughly the size of South America and has a complex network of faults and fractures. It also has a similar pressure to Earth's, which is approximately the same at sea level.
