Earth's nearness to Venus is a matter of perspective. The planet is nearly as big around as Earth. Its diameter at its equator is about 7,521 miles (12,104 kilometers), versus 7,926 miles (12,756 kilometers) for Earth. From Earth, Venus is the brightest object in the night sky after our own Moon.

Asked if the surface of Venus is likely to be life-bearing today, we can give a quick answer: a hard “no.” Further, Venus may hold lessons about what it takes for life to get its start – on Earth, in our solar system, or across the galaxy.

- Summary
Astronomers believe Venus and Earth formed around the same time.Both planets have a rocky core and silicate rock/metallic composition. This is why they are both called “terrestrial planets” along with Mercury and Mars.Earth and Venus have similar sizes. Venus is only about 5% smaller than Earth.They also have almost the same density. Again, with Venus being only 5% less dense than our planet.Venus’ cloudy atmosphere gives it a yellow/white color while Earth looks blue from afar.Venus rotates in the opposite direction as Earth. If you were to stand in Venus’ surface, you would see the Sun rise in the west, and set in the east.Venus also rotates veeery slowly. One single day in Venus is about 243 Earth days.Venus is extremely hot compared to Earth. It can reach 477 °C (750 K) on its surface. In fact, Venus is the hottest planet in the Solar System. This is because of the greenhouse effect all the CO2...Venus and Earth are very similar in size, mass, density, and element composition.The atmospheres, temperature, and surface of the planets are significantly different, making Venus a toxic and inhabitable environment.Venus is sometimes referred to as Earth’s twin because of its similarities.One day on Venus – the time it takes the planet to complete a full rotation on its axis – is equal to 243 days on Earth. That is actually slower than the time it takes for Venus to complete one orbit around the Sun, which takes 225 Earth days.
Jun 17, 2024 · One day on Venus (the time it takes to rotate once on its axis) is equivalent to 243 Earth days, and it does so more slowly than its own orbital period around the Sun, which is about 225 Earth days. This means that on Venus, a day is longer than a year.
Nov 11, 2024 · The period of its orbit—that is, the length of the Venusian year—is 224.7 Earth days. As Venus and Earth revolve around the Sun, the distance between them varies from a minimum of about 42 million km (26 million miles) to a maximum of about 257 million km (160 million miles).
