10 Interesting Venus Facts
Venus facts is the planet that have similar in structure and size to earth, a dim world of intense heat and volcanic activity. The scorched world has temperatures hot enough to melt lead. Glimpses below the clouds reveal volcanoes and deformed mountains. Venus spins slowly in the opposite direction of most planets. Here are the 10 interesting Venus facts.
1. Venus really is the Earth’s twin. Earth and Venus have very similar size and mass, and they orbit the Sun close to the Sun in very similar orbits. The size of Venus facts is only 650 km less than the size of Earth, and the mass of Venus is 81.5% the mass of the Earth. The atmosphere of Venus is 96.5% carbon dioxide, with a runaway greenhouse effect that raises temperatures to 461Â° C.
2. Venus can be so bright it casts shadows. Only the Sun and the Moon are brighter than Venus. Its brightness can range between -3.8 to -4.6 magnitude, but it’s always brighter than the brightest stars in the sky.
3. The atmosphere is very hostile. Although it’s similar in size and mass to the Earth, the atmosphere of Venus sets it apart. The mass of the atmosphere is 93 times that of the Earth’s atmosphere. Temperatures on Venus can rise to 460Â° C. And there are thick clouds of sulfur dioxide on Venus that rain down sulfuric acid.
4. Venus rotates backwards compared to the other planets. Venus facts, rotates very slowly. While a day on Earth takes just 24 hours to complete, a day on Venus is 243 of our Earth days. Venus rotates backwards compared to all the other planets in the Solar System.
5. Many probes have landed on the surface of Venus. During the height of the space race, the Soviet Union launched a series of Venera spacecraft to attempt landings on the surface of Venus. But they underestimated just how nasty the atmosphere can be. The early spacecraft were crushed as they passed down through the atmosphere. Further missions lasted longer, and even returned the first color images of the surface of Venus.
6. People used to think Venus was tropical. Until the Americans and Soviets sent their first spacecraft to study Venus up close, nobody really knew what was down under the planet’s thick clouds.
7. Venus has no moons. Venus looks less and less like our twin. Unlike the Earth, Venus facts has no moons.
8. Venus facts has phases. When looking through a telescope, you can see that Venus goes through phases, like the Moon. When Venus is closest, at its brightest, it actually makes a thin crescent. And then, when Venus is dimmest and furthest away, you see more of a circle.
9. The surface of Venus has few impact craters. Planetary scientists estimate that the surface of Venus is only half a billion years old. The constant volcanism reshapes the surface, covering over any impact craters regularly.
10. There’s a spacecraft there right now. Many spacecraft have traveled to Venus, but one of the most sophisticated is there right now: Venus Express. The mission was sent by the European Space Agency, and arrived at Venus on April 11, 2006. It will perform a detailed study of the Venusian atmosphere and clouds and will map the planet’s plasma environment and its surface. It’s the other interesting Venus facts.
