15 Interesting Facts about Venus
Venus is sometimes referred to as the Earth's sister planet, as in many ways there are similarities - for example, both are about the same size, have a central iron core and a molten rocky mantle, and also have a similar strength of gravity.
There are also some big differences too, however, especially Venus's nasty atmosphere, which you could say makes it more of Earth's evil twin, rather than a sister!
Here are my 15 interesting facts about Venus, I hope that you enjoy reading them and find them fun!
1. Venus measures 7,522 miles (12,100 km) in diameter, which makes it slightly smaller than the Earth. Compared to the other planets, however, the differences in size are very small.
2. The planet rotates very slowly. That means that a day on Venus lasts a whopping 243 Earth days!
3. One of the strange things about Venus is that it rotates clockwise. That might not sound terribly odd, until you realize that all the other planets in the Solar System move in the opposite direction (counter-clockwise)!
4. The planet's atmosphere is very dense, consisting mainly of carbon dioxide with a small amount of nitrogen.
5. The planet is named after one of the most well-known Roman goddesses, who stood for love, beauty, sex, fertility, prosperity and desire.
6. Venus is the second planet from the Sun and travels on a path between Mercury and the Earth.
7. The gravity on Venus is similar to Earth, but the pressure of the atmosphere is much greater because it is so much denser.
8. The planet has a central iron core and a molten rocky mantle, rather like the Earth.
9. Unlike most planets in the Solar System, including the Earth and Mars, Venus has no moons.
10. Because Venus is easily visible to the naked eye, it features in many world mythologies. The first written accounts of the planet are by the Ancient Babylonians in 1600 BC.
11. Venus is one of the brightest things in the sky, along with the Sun and the Moon. At one time people thought that it was two separate bodies, which they called the morning star and the evening star.
12. Venus is covered by dense clouds of acid. The clouds stop heat escaping and make it the hottest planet in the Solar System.
13. Because the planet is covered with cloud, nobody knew what it really looked like until the Soviet Union managed to land a Venera 8 spacecraft on its surface. Before it was discovered how hostile the atmosphere was, Science Fiction writers speculated that there might be tropical jungles on Venus.
14. The reality is that the surface of the planet is mainly composed of cratered desert. It has many active volcanoes, some of them extremely large. Storms rain down corrosive sulfuric acid.
15. The most recent (successful) Venus exploration mission was launched in 2005. The spacecraft, Venus Express, is funded by the European Space Agency and has been orbiting and sending back information about Venus since 2006.
Facts About The Solar System
- Our Solar System is thought to be more than over 4.5 billion years old.
- It composed of the Sun, 8 planets, 5 dwarf planets, more than 160 moons, 500,000 asteroids, over 3,000 comets, as well as plenty of dust, and gas.
- There are estimated to be several billion other solar systems in the Milky Way Galaxy.
- Although there is some disagreement, the solar system is estimated by some to be almost 2 light years across.
- Scientists have split the Solar System up into a number of regions: the inner region consists of the terrestrial planets Mercury, Venus, Earth, and Mars; next comes the the Asteroid Belt; then the outer gas giant planets of Jupiter, Saturn, Uranus, and Neptune, then the Kuiper Belt, and finally the Oort Cloud.
