  • 165629 October – Edmond Halley, scientist (died 1742)source
  • 1656November 8 – Edmond Halley, English scientist (died 1742)source
  • 1673July 24 – Edmund Halley enters The Queen's College, Oxford, as an undergraduate.source
  • 1682August 23 – A comet that will later become known as Comet Halley, is observed from several locations on Earth after reaching magnitude 2 and becoming visible to the naked eye. Arthur Storer sees it from the North American colony of Maryland, while German astronomer Johannes Hevelius measures it from Danzig (now Gdansk in Poland). Edmond Halley successfully predicts that it will return in 1758.source
  • 1682September – Halley's Comet makes an appearance, and is observed by Edmond Halley himself.source
  • 1684January – Edmond Halley, Christopher Wren and Robert Hooke have a conversation in which Hooke later claimed not only to have derived the inverse-square law, but also all the laws of planetary motion attributed to Sir Isaac Newton. Hooke's claim is that in a letter to Newton on 6 January 1680, he first stated the inverse-square law.source
  • 1684August – Edmond Halley goes to Cambridge to discuss the problem of planetary motion with Isaac Newton.source
  • 1684December 10 – Isaac Newton's derivation of Kepler's laws from his theory of gravity, contained in the paper De motu corporum in gyrum, is read to the Royal Society by Edmond Halley.source
  • 168410 December – Isaac Newton's derivation of Kepler's laws from his theory of gravity, contained in the paper De motu corporum in gyrum, is read to the Royal Society by Edmund Halley.source
  • 1693English astronomer Edmond Halley studies records of births and deaths in Breslau (Poland), producing a life table consolidating year of birth and age at death. He uses this to work out the price of life annuities.source
  • 1700September 6 – Edmond Halley returns to England after a voyage of almost one year on HMS Paramour, from which he has observed the Antarctic Convergence, and publishes his findings on terrestrial magnetism in General Chart of the Variation of the Compass.source

18th century

  • 1705Edmond Halley publicly predicts the periodicity of Halley's Comet and computes its expected path of return in 1758.source
  • 1715May 3 – A total solar eclipse is seen across southern England, Sweden and Finland (the last total eclipse visible in London for almost 900 years). English astronomer Edmond Halley (who is using the old style Julian calendar date of April 22) records the first observation noted of the phenomenon of "Baily's beads", in which higher elevations on the moon can be observed obscuring portions of the light moments before and after totality.source
  • 171830 April – the proper motion of stars is demonstrated by Edmond Halley.source
  • 1720February 10 – Edmond Halley is appointed as Astronomer Royal for England.source
  • 172010 February – Edmond Halley is appointed Astronomer Royal by George Isource
  • 1742January 14 – Edmond Halley dies; James Bradley succeeds him as Astronomer Royal of Great Britain.source
  • 174214 January – Edmond Halley, astronomer (born 1656)source
  • 1742January 25 – Edmond Halley, English astronomer (born 1656)source
  • 1758December 25 – Halley's Comet is sighted by Johann Georg Palitzsch, confirming Edmund Halley's 1705 prediction of its periodicity.source
