Transit of Venus

By Nick Lomb

Subjects: History, Venus (planet), Astronomy, Observations, Transit

Description: "Every so often, the planet Venus does something remarkable. Its orbit brings it to a point directly between the Sun and the Earth, where it appears to us as a black dot moving across the bright disc of the Sun. This transit of Venus is rare, occurring in pairs eight years apart and then not for more than a hundred years; it has fascinated astronomers for centuries."--Introduction.
