It's time to visit Venus. On Venus, a day lasts 243 Earth days. On Venus, a year lasts 225 Earth days. The difference doesn't matter since both sides have 12 months of 10 Earth days each.
The average temperature on Venus is 450 degrees Fahrenheit (230 degrees Celsius). It has an atmosphere made mostly of carbon dioxide with a small amount of oxygen present at the top of the atmosphere.
Venus orbits very close to the sun. But because it has no water, there is no tidal force so it stays roughly the same size as far as we can tell. This means that over time, its surface will be destroyed by erosion caused by the solar radiation melting anything within a few hundred miles of the surface.
People have wondered if there is life on other planets. Now we know that there is life on Earth that cannot see, hear, or feel but that still lives in the underground. Also, there are animals on Venus that live in extreme conditions. If there is life on other planets, it could exist in places where nobody would ever think to look.
Because a day on Venus rotates much slower than a day on Earth, a day on Venus is much longer than a day on Earth. On Venus, a day lasts 243 Earth days, or 5,832 hours! On Earth, a day lasts 23.943 hours. Venus, like the Earth and the majority of the other planets, rotates backwards. It is also the only planet that rotates in the opposite direction to Earth.
Venus was once thought to be a paradise Earth, but now we know it has severe weather changes, including windstorms that can reach 250 miles per hour. There are areas where water may have frozen into rocks beneath its surface for many years before being released when those rocks melt from the heat of deeper penetration by the sun's rays.
People have been to Venus, they just don't talk about it too much. The first person to walk on Venus was Soviet scientist Leonid Sedov, who did so in 1990 after making two flights over the planet using data collected by his crew member during their own visit. He found conditions there very hostile; the temperature reached 450 degrees Celsius (860 degrees Fahrenheit), with 95% humidity and no air pressure. Because oxygen is an explosive gas at these temperatures, Sedov had to wear a suit packed with oxygen tanks to avoid asphyxiation.
Visitors to Venus would experience some extreme weather changes.
A single Venusian spin takes 243.0226 Earth days, according to the findings. That implies a day on Venus lasts longer than a year, as Venus completes its circle around the sun in 225 Earth days. The reason for this extreme imbalance in length is simple: Venus is always dark with no sunset or sunrise because it orbits so close to the sun.
Venus has two different hemispheres - one hot and dry, the other cold and wet. As you would expect, they are also equally divided between light and darkness for 8 months each. But due to its extremely eccentric orbit, Venus passes through all four seasons during its 243-day rotation. Spring occurs when the planet is south of the earth; summer, when it is north; autumn, when it is west; and winter, when it is east.
The atmosphere of Venus is made up of carbon dioxide (95%) with small amounts of oxygen (5%). There is evidence that once upon a time Venus may have had water on its surface, but today it is completely covered by an ocean of sulfuric acid.
The average temperature on Venus is 450 degrees Celsius (890 degrees Fahrenheit), but parts of it reach over 700 degrees Celsius (1300 degrees Fahrenheit).
Venus has the longest day; a day on Venus lasts 243 Earth days. A day on Venus is longer than a year on Earth; a year on Venus is just 224.7 Earth days long. On Mercury, a day lasts 58.7 Earth days. On Jupiter, a day is 12 hours 39 minutes 56.9 seconds long. On Saturn, a day is 30 hours 46 minutes 20.4 seconds long.
The sun will go down about 10 miles over the Sahara Desert at midday in Morocco. It will rise again at sunrise about 18 miles over the Pacific Ocean near Easter Island.
On Earth, no place is more than 6 degrees away from the equator, so all points on our planet have essentially the same amount of daylight throughout the year. The only real exception are places close to the poles, where night covers the earth for most of the year.
But even there, you would never notice it because the polar regions are so desolate that there's nowhere to go during the night. And even if there were people around, they would probably be asleep too. Night and day seem very short on Mars. Its days are shorter than Earth's, but its nights are much longer. Thus, its annual cycle takes about 687 Earth months to complete.
All over Mars, you can see rocks that were once part of a Martian volcano.
Venus is 108 million kilometers (68 million miles) from the Sun. A day on Venus lasts approximately 243 Earth days. It takes Venus about 225 Earth years to orbit the Sun.
Earth and Venus are the only two planets that can be seen with the unaided eye. The other planets can only be seen with a telescope. Even though Venus is often called the "Earth's Twin," they are not quite the same size or have the same amount of air as we know it. Instead, they are very similar in size to Mars.
Both Earth and Venus were once able to support life, but neither one does so today. This is because both planets lost most of their original atmosphere through volcanic activity and cosmic radiation. There are areas on both planets that still appear bright enough from space to be visible with the naked eye, but these regions are too small to see from the surface.
Astronomers use telescopes to look at objects across the universe. On March 2, 1990, scientists watched as something unusual happened to Venus: It disappeared from view. An asteroid known as 90 Anti-Virga collided with Venus' atmosphere, causing it to evaporate into space.
While the Earth takes 23 hours 56 minutes 04 seconds to complete one rotation, Venus takes 243.16 "Earth days" to complete one rotation. Because Venus is closer to the Sun, its year is shorter than Earth's, lasting 224.7 days, hence a day on Venus is actually longer than its year.
The average distance between the Sun and Venus is 149.6 million km (95.9 million miles). When viewed from Earth, Venus appears to move across the sky as it rotates, since its orbit is almost perpendicular to ours. But because of its rapid rotation, it actually stays in the same place within our atmosphere.
Venus was once thought to be Earthlike until scientists discovered that it has clouds and air currents similar to those on Mars. They know this because probes have been sent to both planets over the years and found they use the same kinds of fuel.
But while we can learn a lot from exploring other planets, we would not want to live there. The pressure is almost 100 times that of Earth's atmosphere, the temperature varies between 500 and 450 0 Celsius (930-900 Fahrenheit) and sulfur dioxide gas emissions are 30 times more than what Earth's atmosphere contains.
It is because of these reasons that life as we know it cannot exist on Venus. However, some scientists believe that there may be life beneath the surface that we could never reach using current technology.
