Venus
Venus is one of the brightest objects in the sky, so it is clearly visible to the naked eye. It can be tricky to see because it is always near the Sun. So it rises and sets with the Sun each day. Venus rotates "backwards," so the Sun rises in the west and sets in the east. Ancient civilizations believed they were actually two different objects, so they called the one, which rose the Morning Star, and the one, which sets the Evening Star. Astronomers figured out that it was one object. Venus formed about 4 Billion years ago. At the conclusion of forming, it continued to be hit with leftover material. Venus warmed from the inside and separated into layers. Since Venus is so close to the sun, the atmosphere formed differently than Earths. Venus is known as earth's sister planet. In some ways they are very similar. Venus is a little smaller than Earth (95% of Earths diameter and 80% Earths mass). Both have few craters indicating young surfaces. From the similarities, it was thought that below its dense clouds, Venus might be very earth like and might even have life. However, with more detailed study, Venus is different than Earth in many ways. Venus has a slow rotational period, single plate surfa
The space missions to Venus have shown us that its surface is covered with craters, over 1600 volcanoes, mountains, large high land terrains, and vast lava plains. Mercury has only been visited by one spacecraft, but Venus was much luckier. The first spacecraft to visit Venus was Mariner 2 in 1962. It was visited by many others (more that 20 in all so far). Pioneer Venus and the Soviet Venera 7 were the first spacecraft to land on another planet. Galileo figured out that the swirling structure was sulfuric acid clouds. Since Venus is an inferior planet, it shows phases when viewed with a telescope from the perspective of Earth. Galileo's observation of this phenomenon was important evidence in favor of Copernicus's heliocentric theory of the solar system. While all of the planets orbit in an ellipse, Venus' orbit is the closest to a perfect circle. No one actually knows who really discovered Venus. However, much has been discovered about Venus in the past century. ce, lack of a satellite, extremely weak magnetic field, lack of water, high surface temperature, and dense atmosphere. These are the differences but we still have a lot to learn about our "Sister Planet." Venus is the closest planet to Earth, and second closest to the sun (Mercury the closest). However it is constantly covered with poisonous clouds (mostly Carbon Dioxide). The surface can never be seen. Carbon dioxide atmosphere creates a strong greenhouse effect, which traps heat in the atmosphere. In Venus, there are too many greenhouse gases, which cause the temperature to incr
