Transit of Mercury Pin

This pin is what i like to refer to as, an updated version of documenting the sun on a special occasion. There are many drawings and such that document the sun and moon so i wanted to do it in a different way. In this case, on November 8th, 2006, Mercury transited the sun, meaning it came between the Earth and sun, and so was visible crossing the disc of the sun. you can see the drilled holes to represent Mercury's path, with the blackened rivet denoting the current postion, as well as any current sun spots and flares. It is made of brass, and has a dome shape. Surface was sandblasted and colored with color pencils. dimensions are 2" x 2" x .5"
