How does a transit compare with a total eclipse of the Sun?
Unquestionably, the Venusian Transit in 2004 won’t compare to a total solar eclipse. If you did not know the transit was happening, you wouldn’t notice anything unusual at all. The sky doesn’t get dark, stars and planets don’t come out, and there is no dramatic change in temperature, wind, or humidity. However, the event is so rare that it is worthwhile to expend the effort to go see it, nevertheless.
