Transit of VenusIn 1631, the transit of Venus occurred as first predicted by Johannes Kepler. He correctly predicted that an ascending node transit of Venus would occur in Dec 1631, but no-one observed it - due to the fact that it occurred after sunset for most of Europe. Kepler himself died in 1630. He not only predicted this particular transit but also worked out that transits of Venus involve a cyclical period of approximately 120 years. When such a transit is observed, Venus appears as a small black circle moving across the face of the Sun. None occurred during the twentieth century, but the next happened on 8 Jun 2004. |
