History
The Venus transit is a very exciting astronomic event, like a supernova, which can be seen with your own eyes or a bigger comet. Each of them is not so usual and is appreciate not only by astronomies, but even by laymen. In the past were the transits very important, because people didn’t know exactly the distance between the Earth and the Sun-the Astronomic Unit AU. 1631 Pierre Gassendi 1761 J.Horrocks, W.Crabtree 1796 J.Coock + 150 astronomies 1874,1882 First photographs |
