VENUS TRANSIT 8/JUNE?2004


You are Visitor#
Dear science and astronomy friends,
Mercury glided in front of the Sun Disk on 7 th MAY 2003. That is more frequent than VENUS GLIDE in front of SUN (only 12 times in 1000 years. That you will get Chance on 8 th JUNE 2004
Please do not watch the sun directly to save your eyes.)
On 8th June 2004 the planet Venus will cross the Sun's disk as seen from Earth. It will cut into the solar disk at about 5:20am in the morning and will pass off the other limb at about 11:23am. The last occasion on which this happened was 1882, over a century ago.
Looking at the Sun at any time is potentially dangerous and can result in serious eye damage or blindness. The safest way to view the Sun is indirectly using a projection method.
VENUS Radius vector: 0.7261900 AU (109 million km) and SUN Radius vector: 1.0150791 AU (152 million km)
ON 8th June Venus is at 0. : 0.7262 AU from Sun so 0.2889 AU from Earth (1.0150791-0. 0.7262). And VENUS Diameter is 12012KM which covers area of Sun about 12012 x 1.0151/0.2889 = 42206 Km Sun area. This is greater part of the Sun than VENUS Diameter.
Sun D= 1391980 and divide by area covered by VENUS 42206, Gives us how big area of Sun is covered by Planet Venus of 12012 Km diameter. 1391980 /42206 =32.98. So it covers nearly about 1/33of the Sun.
You may view the Sun directly only through a special filter made for safe solar viewing. If you are not certain that a filter is approved and safe or you have any other doubts - DO NOT USE IT.

As you can see from the list below, transits of Venus across the Sun's disk are very rare (there are only about 12 per millennium!). We are quite lucky that two transits are going to happen in the next few years although the second one is only partially visible from some parts of Europe.
There is a curious 243 year repeating pattern with two transits in December (around the 8th) 8 years apart. Then wait 121 and half years, then two June transits (around 7th), again 8 years apart. Then wait 105 and half years and the pattern repeats again
