Late in the afternoon of June 5, 2012, the planet Venus will cross (or “Transit”) the sun. This won’t happen again for 100 years!!
You can watch Venus cross the sun with the same safe glasses used for watching the May 20, 2012 eclipse of the sun.
Venus will appear very small. Even though Venus is the size of the earth the sun is 100x bigger! It should look something like this:
If you want to safely look at a larger image of the sun,use binoculars to project (NOT look at!) the sun. Practice WELL in ADVANCE of eclipse day!
Using binoculars to project the sun is much easier if they are supported on a tripod. Camera stores can help you with this. Here is a nice binocular to camera tripod holder.
