Twin earth, as he called them the past both have the same size, mass and density, both of which are at the same time and Nebula one, but this twinning has ended when he was studying the planet's close, I have discovered that Venus differs completely from the ground, there are no oceans on the planet and surrounded by a membrane heavy aerial component of carbon dioxide for the most part there is no trace of the water and dragging it and rain of sulfuric acid on the surface and atmospheric pressure equivalent to 92 times Earth's atmospheric pressure at sea level.
Scorching heat on the surface of up to 482 degrees Celsius, the heat formed by dense atmosphere composed of carbon dioxide, which causes the phenomenon of glass houses, passing the sun through the atmosphere is thick and increase the temperature of its surface is not allowed to go out to outer space that makes it Venus hotter than Mercury is closest to the sun.
The day on Venus equals 243 days, the biggest landslide of the year of 225 days the amount of ground, and going on the planet from east to west, the sun seems to the inhabitants of Venus rises from the west and sets in the east.
Until recently, scientists can not study the geography of the planet's surface the intensity of withdrawal, which obscure the vision of telescopes normal, but with the development of the telescope radio could see through these clouds, and there were trips successful to the planet, including Pioneer in 1978 and Magellan in 1990 and 1994 and flights American, and Russian flight Venera 15.16 in 1983 and 1984 was provided that sufficient flight scientists to study the images of the planet and its surface.
The surface of Venus is relatively new in terms of geography, it is clear that the surface was re-configured for 300 to 500 million years ago, which makes scientists puzzled how and why this happens, the topography of the planet consists of broad plains covered with lava, mountains and hills formed by geological activity.
High Max Montes in Ishtar is the highest peak on Venus, and Aphrodite is the highest region extending halfway around the equator of the planet. Photos taken by the voyage of Magellan to the high ground to show that about 2.5 miles from the glitter of an unusual and distinctive soil moist, and in any case there is no liquid water on the surface of the planet or they gathered in the land. And the proposed theory for this is a pool of mineral components, studies have shown that these substances as possible it is one of the components of iron, these components do not settle on the plains and probably settled on the highlands, it is possible that the metal strange the other give the same results, but the focus is less.
Fill drilling of the many and scattered the planet's surface, drilling, are small less than 2 km and is located by the atmosphere heavy, but the exception is occurred due to the fall of large meteoroids split before impact, its surface is composed combine drilling, covering volcanoes and impact the planet's surface, at least 85% of its surface is composed of lava volcanic lava, which pumps a terrible stretch to hundreds of kilometers and extended to the lowlands to be the vast plains. More than one hundred thousand small volcano in addition to hundreds of volcanoes, huge lava come out to the surface of the planet, this flood of lava form of streams or paths many complex extends for hundreds of kilometers, and there one of them extends to about 7000 kilometers across the planet.
