Venus The Second Planet.....


Venus is sometimes called Earth's sister Planet. It most nearly matches Earth in size, and it's orbit is closest to Earth's orbit. Its very dense atmosphere is composed mostly of carbon dioxide (co2). Opaque white and yellowish clouds hide its surface. Because of the highly reflecting clouds and its close approaches to Earth, Venus is very BRIGHT when it appears in our sky. Like Mercury, it moves only a small angular distance from the Sun as seen from Earth. When it moves into a position to be our Evening Star or Morning Star (setting or rising a few hours after or before the Sun) It is BRIGHTER that any other Planet and is some 15 times brighter than the brightest star (Sirus);it can even cast shadows. Through a telescope, Venus appears as a nearly blank disk, occasionally mottled by barely visible dusky bands or patches.
