At its closest approach, it is about 25,000,000 miles(40,200,000 kilometers) away from earth.As seen from earth, Venus is brighter than any other planet or even any star. At certain times of the year Venus is the first planet or star in the western sky. At other times its the last planet to be seen in the eastern sky.
