By the time of the long predicted transits of Venus in 1761 and 1769, an international collaboration of observers had been set up under the direction of the French astronomer Delisle-although hostilities between France and England did little to assist matters. The frigate on which Charles Mason ...
A prediction of the 1761 transit of VenusMarriott, R. A.Journal of the British Astronomical Association
He originally planned to use transits of Mercury to help in measuring the length of the astronomical unit, but Venus would be a much more satisfactory target, partly because it is closer and also because it is larger. As long ago as 1716 Halley had delivered a paper to the Royal Society,...
of a partialeclipseof a body (star, planet) by another body orbiting the first one. The transit refers to the whole duration of the phenomenon. Historically, the observations of the transit of Venus in front of the Sun as seen from Earth, and especially the ones in 1761 and 1769, have ...
Venus will cross the sun's face from Earth's perspective on Tuesday (June 5; Wednesday in much of the Eastern Hemisphere), marking the last suchVenus transituntil 2117. Scientists once chased planetary transits in an attempt to size up thesolar system, but this transit of Venus will be put...

Venus is always a small object in the Earth's skies, even the several weeks a year it presents us with the largest planetary disk of our Solar System as seen from Earth, when Venus is closest to us. (Fortunately during the rare Transits thisISthe case!) In physical size, Venus is a...
A transit of the planet Venus across the brilliant face of the Sun is one of the rarest of all astronomical phenomena. Such transits occur in pairs just eight years apart, but following the second transit of a pair, the next will not occur again for more than a century. Transits of Venu...
