Description

The Transit of Venus is a celestial event that occurs when Venus’s orbit causes the planet to speed past the slower moving Earth and visibly cross the Sun, partially obscuring it. The Transits of Venus occur in pairs that are eight years part and tend to be separated in time by just over a century. The first person to predict and observe the Transit of Venus was James Horrocks, on Dec. 4, 1639. There were also Transits of Venus observed and recorded in 1761, 1769, 874 and 1882. The 2012 Transit of Venus will be visible in the Americas on the evening of June 5, 2012. The next transit does not occur until 2117. This vol. contains observations of the Transit of Venus on June 3, 1769, recorded by David Rittenhouse, who observed the transit in Norriton, PA; and John Ewing, who observed the Transit of Venus on June 3 and the Transit of Mercury on Nov. 9, 1769, in the State-House Square, Philadelphia.
