While hard facts, such as Venus' circumference, diameter, and distance from the sun are relatively easy to determine, historical and future implications of the planet and its study are not as simple to calculate. Two of the most important facts that we don't yet know about the planet Venus are the significance of its historical positioning and its implications for earth's atmospheric problems.
According to Ev Cochrane's study into the ancient solar system, the regularity with which the system now moves around the sun is a "recent development." In the ancient world, instead, Cochrane suggests that observers noted a different type of solar system. The discrepancies between the two solar systems has largely to do with the planet Venus. According to Cochrane, Venus' movement into its current orbit was recent, and this movement created solar side effects that may be important to the current development of the solar system. While Cochrane's theory may be incorrect, one of the most important facts that we don't know about Venus and much of the solar system are the facts about its evolution. In order to learn more about Venus and its role in the solar system, astronomers should carefully compare its placement in the current solar system with that of the ancient solar systems drawn and witnessed by classic philosophers and astronomers. Additionally, by studying Venus, researchers hope to determine both the highest levels of C02 and highest temperatures that can sustain human life and the "future habitability" or earth as the sun grows warmer and C02 in the atmosphere continues to rise. A 2010 Japanese mission was scheduled to investigate these questions. ("Missions to Venus," "Japan Plans").
In addition to Venus' historical positioning, a fact that may have implications for the current position of Venus and the solar system, we do not know enough about Venus' atmosphere to use it to draw conclusions about Earth's atmosphere. What we do know about the atmospheres of both planets, however, is that C02 is an important element. For Earth, C02 has begun to cause major problems in the ozone layer and in terms of greenhouse gasses and global warming. For Venus, C02 makes up most of its atmosphere. In fact, the reason that Venus reaches such high temperatures is because of the "

Thus, while scientists know a great deal about the planet Venus, they remain still unaware of the more abstract implications of the planet's status. By learning more about the planet's historical position and the atmospheric quality as compared with Earth's, Venus' importance as a planet can be understood.
Conclusion
Although Venus has maintained a position in mythology and religion as a rather mysterious planet, scientific research has suggested that quite a bit is actually known about the planet. The questions that still remain to be answered by Venus, however, allow the planet to retain some if its mystery.

At the Poles, the Sun circles around the horizon forever. At the Equator, it rises vertically at the East point on the horizon, passes directly overhead, and then sets vertically at the West point on the horizon (Seligman). These same mechanics should apply for other solar and planetary systems as well. As an example, the seasons on the other planets in our solar system compare to the seasons on the
Astronomy The Terrestrial planets are defined as rocky planets or telluric planets, and they are Mercury, Venus, Earth and Mars. These planets have a lot of similarities that allow them to be grouped together, especially in contrast to the Jovian or gas planets. The telluric planet is one given type of planet, defined as one that is primarily composed of rocks and heavy metals. Thus, the composition of these planets is
Libguide to Planets: A Concise Look at the Solar System and Its Constituent Elements This libguide provides a comprehensive listing of peer-reviewed, scholarly and non-reference material including fiction, non-fiction, poetry, folklore, audio, video, and other teacher resources. INTENDED AUDIENCE: The intended audience for this libguide is educators, but parents and older students will find the content useful as well.

In conclusion, both of these planets, which are closest to the Earth in miles, are a world away in their weather and atmosphere. Mars is a desert planet of extremes that can be exceedingly cold and enormously windy, while Venus is a planet covered in clouds and extremely hot. Both planets have several weather-related events that are quite similar to Earth, but there are shocking differences, as well. As scientists
Extra-Solar Planets The word planet means "wanderer" in Greek. It derives from the fact that planets within our solar system seem generally to wander eastward about the so-called fixed stars across the zodiac constellations (Kolb). There is no clear consensus precisely defining what constitutes a planet, as distinguished from brown dwarfs, which are the material remnants of burned out ancient stars whose masses where too small to form white dwarfs or
Astronomy Uranus Uranus was the first planet discovered in contemporary times. It was discovered in 1781 by William Herschel while he was searching the sky with his telescope. It had actually been seen many times before but ignored as simply being another star. "In the beginning Herschel named it "the Georgium Sidus" (the Georgian Planet) in honor King George III of England. Others called it "Herschel." The name "Uranus" was first proposed
