Plannet Venus Transit Across the Sun will 5th/6th June 2012

Many of us rember the last transit of venus
A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. The duration of such transits is usually measured in hours (the transit of 2004 lasted six hours). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is almost four times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth.

Transits of Venus are among the rarest of predictable astronomical phenomena.The next transit of Venus will occur on 5 and 6 June 2012, and will be the last Venus transit this century.The Venus will vissble like a smaal black disc in front on sun for nearly 6 hour and after that the venus will visible in 2117 and most of us is not alive at that time

This phenomenon belongs to the series only two transitions 21st century the first of which took place on 8th June 2004.
