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 surface, 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."
            
             The interior of Venus is probably similar to Earth's interior. Venus, like Earth, is one of the terrestrial planets and is made of rock and metal. It probably has a partly molten metallic core, a rocky mantle, and a crust. The surface of Venus consists of 2 large continents which are Ishtar Terra, found near the north pole of Venus and Aphrodite Terra, found near the equator of Venus. It has mountain ranges, and a few large islands. There are craters that show, liquid once f...
