The Sun is in the center and the solar system is always in motion. In June of 2004 a of Venus will take place when that planet passes directly between the Earth and the Sun. This is a that is very rare as its occurence has only been observed six times before now. When this happens, Venus appears as a small black dot on the surface of our Sun.
Here are some interesting facts about Venus. Venus and Earth are similar in size. They differ in that Venus does not have ocenas or human life, and its temperature during the day reaches 484 degrees Celsius. That temperature is high enough to melt lead. Venus spins very slowly as it revolves around the sun in a circular . It rotates slowly on its in a clockwise direction. That is the opposite direction from any other of the planets.
