Because Venus has an axial tilt of only 2.7 degrees, it lacks the seasons found on both Earth and Mars. Venus also has a very thick atmosphere and suffers from a runaway greenhouse effect, meaning that the surface of the planet experiences no temperature variations whatsoever.
Seasonal changes are the result of the angle at which a planet spins upon its axis. Warmer summer temperatures are experienced by a hemisphere that is tilted toward the sun, while the opposite hemisphere can expect cooler winter temperatures. While the planet Venus is similar to Earth in many respects, its axis is tilted at a much narrower angle.
Venus has an atmosphere that is 93 times thicker than Earth's. Due to its density and the presence of high quantities of carbon dioxide, the greenhouse effect of the atmosphere traps a great deal of heat from the sun and distributes it around the surface of Venus. Temperatures on the surface of Venus average 860 degrees Fahrenheit, regardless of location. Venus rotates much more slowly than Earth, and some areas of the planet may be without direct sunlight for up to 50 Earth-days. Even the difference between the long day and night of the planet is unable to change surface temperatures.Learn More
The eight described planets all orbit the Sun at different distances; Mercury is the closest planet to the sun, followed by Venus, then Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The distances of the planets are normally measured in kilometers, because scientists use metric measurements. However, scientists also use a unit called an “astronomical unit,” which is equal to the distance between Earth and the sun.Full Answer >
Venus is just slightly smaller than the Earth, with a radius of about 3,760 miles and a circumference a little over 23,627 miles. These measurements make Venus about 94 percent of the size of the Earth, although it is only about 82 percent as voluminous.Full Answer >
Venus, the second planet from the sun, is slightly smaller than the Earth and is covered by thick clouds of sulphuric acid that make it difficult to observe its surface. Venus appears as a bright object in the morning sky.Full Answer >
Depending on their orbital progress, Venus or Mars may be the closest planet to Earth at any given time. The distance between Venus and Earth varies between 24 and 162 million miles, and the distance between Earth and Mars varies between 34 and 250 million miles.Full Answer >
