As Venus moves forward in its solar orbit while slowly rotating backwards on its axis, the top level of clouds zips around the planet every four Earth days, driven by hurricane-force winds traveling at about 224 miles 360 kilometers per hour. Charles has a Master of Arts degree from the University of Missouri-Columbia, School of Journalism and a Bachelor of Arts degree from the University of South Florida. Venus has some unique surface features in addition to the impact craters, mountains, and valleys commonly found on rocky planets. Venus has the most circular orbit of all the planets in our solar system. Formation When the solar system settled into its current layout about 4. The planet is aptly named since it makes a beautiful sight in the sky, with only the Sun and the Moon being brighter. She has a Bachelor of Science in Chemistry from the Salisbury University, a Bachelor of Chemical Engineering from the University of Delaware and a degree in Science Journalism from New York University.
Venus is similar in size to Earth. These clouds are so dense that they reflect 60% of the sunlight Venus receives back into space. The surface of Venus is effectively ; it retains a constant temperature not only between day and night sides but between the equator and the poles. This means that any small asteroids entering the atmosphere of Venus are crushed by the immense pressure, which is why there are no small surface craters on the planet. In addition to performing radar mapping similar to that of Pioneer Venus, Magellan also undertook a more advanced radar imaging that gathered much finer details.
As one of the brightest objects in the sky, Venus has been a major fixture in human culture for as long as records have existed. It is covered with holes. This artwork from hundreds of years after the Romans worshiped Venus shows how important her mythology continued to be even after the fall of Rome. Think of the average plastic spoon: a uniform white color, mass produced, and unremarkable in just about every way. A Venusian thus lasts longer than a Venusian year 243 versus 224.
The atmosphere traps heat and keeps Venus toasty warm. Relative dating is an easily understood process that involves stylistically comparing an object whose date is uncertain to other objects whose dates have been firmly established. This is known as a retrograde rotation and may have been caused by a collision with an asteroid or other object which caused the planet to change its rotational path. There is no liquid water on its surface today because the scorching heat created by its ozone-filled atmosphere would cause any to boil away. Venus is by far the hottest planet in the Solar System, with a mean surface temperature of 735 K 462 °C; 863 °F , even though is closer to the Sun. The mission would launch sometime in the 2020s. Ironically, the planet Venus is covered with acid clouds, so the name is not very suitable for a goddess of love and fertility.
One Venusian year is about 1. The 's in 2007 detected further confirming the occurrence of lightning on Venus. Thus, geologically speaking, the Veunsian surface is relatively young. The permanent cloud cover means that although Venus is closer than Earth to the Sun, it receives less sunlight on the ground. On the ground, it would look like a very hazy, overcast day on Earth. It has no oceans, and in fact no liquid water.
Atmosphere Atmosphere Venus' atmosphere consists mainly of carbon dioxide, with clouds of sulfuric acid droplets. In contrast, the sculptor placed scant attention on the non-reproductive parts of her body. He thought the planet had two huge moons orbiting very close to the planet. Too volatile to condense on the surface, it rose in gaseous form to higher elevations, where it is cooler and could precipitate. In combination with the emphasis on the breasts and pubic area, it seems likely that the Venus of Willendorf had a function that related to fertility. A deep canyon is named for Diana, Roman goddess of the hunt.
This implies that the dynamo is missing because of a lack of convection in Venus's core. Venus has a wide variety of volcanic landforms, but there are no tectonic plates. Venus is very close in size to the Earth, 95% of the Earth's radius. Although all are , Venus's orbit is the closest to , with an of less than 0. On Earth, the sun appears to rise in the east and set in the west. For example, was named after the Roman god of agriculture, and name comes from the King of the Roman gods. Archived from on 17 April 2012.
The atmosphere is heavier than that of any other planet, leading to a surface pressure 90 times that of Earth. The ancient Egyptians and Greeks thought Venus was two separate bodies and named them The Morning Star and the Evening Star until in Hellenistic times, people figured out that it was only one object. Venus was the goddess of love and beauty, and the Greek goddess of love and beauty was Aphrodite. The original prime meridian passed through the radar-bright spot at the centre of the oval feature Eve, located south of Alpha Regio. Studies have suggested that billions of years ago Venus's atmosphere was much more like Earth's than it is now, and that there may have been substantial quantities of liquid water on the surface, but after a period of 600 million to several billion years, a runaway greenhouse effect was caused by the evaporation of that original water, which generated a critical level of greenhouse gases in its atmosphere.
We may infer from the small size of her feet that she was not meant to be free standing, and was either meant to be carried or placed lying down. Although Venus is no longer worshiped by large numbers of people, we still remember her in art and science thanks to her widespread influence. Mercury is a little bigger than Earth's moon. Encyclopedia of the Solar System 3rd ed. Atmospheric erosion by the solar wind probably led to the loss of most of Venus's water during the first billion years after it formed. Name of Saturn Where you wondering how did Saturn get its name? Their exact composition remains uncertain; , although many things would need to be ruled out before accepting that conclusion. It has practically no magnetic field.
Physics and Chemistry of the Solar System 2nd ed. The similarity in size and density between Venus and Earth suggests they share a similar internal structure: a , , and. This suggest that any meteroid small enough to create a crater having a diameter less than 2 km would have broken apart and burned up during its passage through the dense Venusian atmosphere. Archived from on 11 July 2012. Venus' high surface temperatures overheat electronics in spacecraft in a short time, so it seems unlikely that a person could survive for long on the Venusian surface. With an axial tilt of just 3 degrees, Venus spins nearly upright, and so does not experience noticeable seasons.
