Live Transit of Venus 2012 Time in Your Country on June 5-6
On June 5-6, 2012, Venus will pass in front of the Sun. The transit of Venus 2012 will be the last chance to view this phenomenon for over 100 years.
Transit of Venus 2012 explained
During the transit, Venus passes between Sun and Earth. The planet becomes visible from Earth as a small dot against the Sun’s disk. Although Venus is almost four times larger than the moon, it blocks a much smaller portion of the Sun’s face than the moon does during a solar eclipse. This is because it is much further away from Earth.
Venus is the second planet from the Sun, Earth is the third. On a clear night Venus can also be seen as a bright “star” in the sky, especially shortly after sunset or before sunrise. This is why it is also referred to as “evening star” or “morning star”.

Transit of Venus Dates History – How often does this happen?
The alignment Earth – Venus – Sun has only occurred 7 times since the invention of the telescope: in 1631, 1639, 1761, 1769, 1874, 1882, and 2004.
The phenomenon can be experienced in recurring intervalls of 8 years, 121.5 years, 8 years, and 105.5 years. The last occurrence was 8 years ago, the next one will be in 105.5 years – on December 11, 2117.
The following chart shows the dates of several Venus Transit pairs and the Venus Transit Cycle.
The times in red reveal the primary cycle. The times in blue reveal the dual sub-cycle occurring between pairs. The times in yellow reveal the duration between the last transit of one pair and the first transit of the second pair.
Transit of Venus 2012 – Watch Live with eye protection
Like observing solar eclipses, viewing the Venus pass before the Sun requires proper eye protection. The sun’s photosphere emits intense infrared and ultraviolet (UV) radiation. Just as UV radiation causes sunburn to skin, it can also damage the retinas in the eyes – but it does so at a much faster rate. The human eye can suffer permanent damage if it is exposed to direct sunlight for a few seconds.
The easiest and cheapest option to protect your eyes while watching the transit of Venus is to buy solar shades, which normally cost around 1 USD.
