Attention question "If we get the sun by a mountain on the east and morning goes by one located to the west, where do we stand? "
But what does it? Everyone knows that the sun rises in the east and sets in the west. So the Cowboys were to start Sun, to discover the far West. This question must be wrong Trivial. Let's see what response da ... Venus!
Venus? "How is that? I'll get online ... Ah, yes. He says that Venus rotates in the opposite direction to Earth. That is, indeed, the sun seems to go in the opposite direction as seen from the surface. I mean, if I understand correctly, if Venus were in when we heard the newsletter on radio would tell us something like "eleven o'clock, an hour in the Canary Islands , rather than" one hour less " as we used to hear.
And what might be going backwards? It is not known for sure, but perhaps there was a large asteroid that collided with Venus holding up or making it go backwards. In fact Venus rotates very slowly and makes a turn on itself in 243 Earth days.
On Earth, day and night cycle is given by the time it takes to rotate on itself, about 24 hours, because at that time has not given much time to move to the Sun But Venus things change. As it take so long a walk, when finished turning upon itself is that the sun has already moved the site and so, night and day cycle at Venus does not match the time it takes to rotate. One day on Venus lasts 116 days and one year 1.92 Earth Venusian days (224 Earth days). Observe
Venus is very entertaining. Venus is the brightest object in the sky after the Sun and Moon, of course. Can not be seen from the Sun, so we can only see in the morning or afternoon. It's what people called the morning star or evening star , respectively, a very bright in the sky that others like to be mistaken for a UFO.
addition, as already noted Galileo 400 years ago, being a planet that is closest to the Sun than the Earth can do with phases (phase increasing, decreasing ...), as if the moon is involved.
The inner planets show phases like the Moon.
is curious that Venus has a temperature of 460 degrees, much larger than Mercury (170 degrees), but is twice the distance from the Sun and that's simply because Venus has a dense atmosphere. The atmosphere of Venus is composed of 96% carbon dioxide and 3% nitrogen at a pressure 95 times greater than on Earth and sulfuric acid clouds covering the planet. Carbon dioxide from the atmosphere does not stop heat escaping into space, the greenhouse known, by increasing the temperature of the surface.

Given the size of Earth and Venus are very similar, look at Venus can give us a clue about what might happen if Earth greatly increased concentration of carbon dioxide, as has happened since we have all agreed to take the car to go get bread.
Because the atmosphere is so dense, only the largest meteor through the atmosphere without burning completely. So there can be only large craters on Venus.

Anyway the surface of Venus is not visible unless they penetrate the atmosphere or using a radar and not an optical telescope around the house. When we do that, we see the surface of Venus full of volcanoes (which are those that emit sulfur into the atmosphere).
we have sent probes to Venus, once last landing shortly before being crushed by the enormous atmospheric pressure they endure. They have just enough time to photograph their feet and say goodbye to Venus photographing a landscape that tells us that Venus not going to make it easy for things if we want to explore.

Despite being called Earth's twin, Venus does not treat us as well as his sister when visiting their surface. Without oxygen to breathe, charred, crushed and corroded by the sulfuric acid clouds. So we would end up on Venus.
