Venus (Venus) away from the sun as the planets are respectively the two largest of the six no moons. Venus has a similar style to the world. It is known as the twins to the world of our planet. The internal structure of Venus consists of a core of iron with a radius of about 3000 kilometers wrapped in the mantle, with a thickness of about 3000 km and the crust is composed of silicate rocks
first spacecraft to travel to Venus is Mario. Scanner 2 in the year 2505, after which there were many. Until the year 2532, Magellan spacecraft used radar to navigate through the dense atmosphere of Venus to map the surface of the star. A survey by the radar, keeping in mind the high level of the surface of Venus. And found that the surface of Venus is covered with volcanoes and plains of volcanic centers. Also found The surface of Venus is no small craters because the meteors are burned out during the fall into the dense atmosphere of Venus
's atmosphere Venus is very dense. The atmospheric pressure on the surface of Venus is higher than the atmospheric pressure on Earth's surface or the equivalent of 90 times the pressure at sea depth of 1 kilometer Venus's atmosphere is mainly composed of carbon dioxide. There are many layers and layers of clouds comprising sulfur dioxide (sulfuric acid), which is several kilometers thick. We can not see the surface of Venus. The dense atmosphere that cause greenhouse heat retention. Surface temperatures up to 470 ° C can be seen that the surface of Venus is hotter than Mercury's surface in spite of the distance from the Sun than Mercury and twice as much time captions 1.
