Venus
Venus has been known since prehistoric times and the planet is named after Venus, the Roman goddess of love. It is the second-closest planet to the Sun and it`s often called Earth's "sister planet," because the two are similar in size, gravity, and bulk composition. Because of these similarities, it was thought that
Venus might even have life. Venus is also called the Morning star or the Evening star, because it reaches its brightness shortly before sunrise or shortly after sunset. It is the brightest object in the sky except for the Sun and the Moon . During the last few years the scientists have found that Venus and Earth are very different. It has no oceans and is surrounded by a heavy atmosphere composed mainly of carbon dioxide with virtually no water vapor . There are strong winds at the cloud tops but winds at the surface are very slow, no more than a few kilometers per hour . The surface of Venus retains a constant temperature between day and night and between the equator and the poles . We can't see the surface of Venus from Earth, because it is covered with thick clouds that strongly reflect sunlight. However , space missions to Venus have shown us that its surface is covered with craters, over 1600 major volcanoes, mountains , large highland terrains, and vast lava plains.
Venus is usually visible with the unaided eye. On June 8 2004, Venus passed directly between the Earth and the Sun, appearing as a large black dot travelling across the Sun's disk . This event is known as a " transit of Venus" and is very rare: the last one was in 1882, the next one is in 2012 but after than you'll have to wait until 2117. Venus orbits the Sun at an average distance of about 108 million km, and rotates once every 243 days . Studies have suggested that several billion years ago Venus's atmosphere was much more like Earth's than it is now, and that there were probably substantial quantities of liquid water on the surface.
