Into Queens College of the University of Oxford in 1673. 1676 to the South Atlantic Shenghelena Island determination of the orientation of the southern sky stars, the completion of the South Star table contains 341 stellar precise location recorded to a transit of Mercury, but also for a lot of pendulum observations. 1678 Harley-Davidson was elected a member of the Royal Society, and was awarded a master's degree at the University of Oxford. In 1684, he went to Cambridge to consult Newton explain the mechanics of planetary motion, inspired by Harley's research progress, Newton expanded his study of celestial mechanics. the

In 1716, he designed a new method of observing the transit of Venus, and hope that through this observation precise determination of the solar parallax and can infer from the Sun-Earth distance, 1718, Harley identify stellar space motion. 1720 successor for a second term Greenwich Observatory,.
