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 first spacecraft to visit Venus was Mariner 2 in 1962. Venus, like Earth, is one of the terrestrial planets and is made of rock and metal. Evidence comes from the number of craters found on the surface. ce, lack of a satellite, extremely weak magnetic field, lack of water, high surface temperature, and dense atmosphere. Some are Atalanta Plantia, Guinevere Planitia and, Lavina Planitia. It takes 243 earthy days to circle the Sun. The Atmospheric pressure is nearly 100 times greater than Earth. However, much has been discovered about Venus in the past century. Galileo’s observation of this phenomenon was important evidence in favor of Copernicus’s heliocentric theory of the solar system. Although heavy cratering has stopped, some cratering continues to this day.
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. Unlike the case of Mars, however, careful examination of the evidence supports the idea that the surface of Venus may be active in a way that is very different from the Earth.
