Q:

Why doesn't Venus have seasons like Mars and Earth do?

A:

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.

    Why does Venus change colors?

    A:

    According to NASA’s Solar System Exploration, everything in Venus appears red because of a thick layer of atmosphere that filters out the actual shades of color. The planet appears bright white when observed from space because of its cloud cover. Its surface rocks are variations of grey, similar to the rocks on Earth.

    How many rings does Venus have?

    A:

    Venus does not have any rings. The planet does not have rings because the temperature on Venus is too high for their formation. Rings are associated with the outer planets of Jupiter, Saturn, Neptune and Uranus

    What is the gravitational pull of Uranus?

    A:

    The acceleration due to gravity on the surface of Uranus is 8.69 meters per second squared. The value of this acceleration due to gravity on the earth's surface is 9.81 meters per second squared. So the gravitational pull of Uranus is 86 percent of that of Earth.

  • Q:

    Why is Earth important?

    A:

    As the only known planet that is habitable for human beings, the Earth’s importance is self-evident. Every living organism known to science obtains all of its resources from Earth, and has very few other options available. Without the Earth, humans would be doomed to extinction, unless they were able to adapt to another planet's conditions before the Earth disappeared.
