Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply Halley. Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC, but it was not until 1705 that the English astronomer Edmond Halley understood that these appearances ...
The details of Edmund Halley's visit to Newton in 1684 are known to us only from reminiscences of thirty to forty years later. According to one of these reminiscences, Halley asked Newton, "what he thought the Curve would be that would be described by the Planets supposing the force of attraction towards the Sun to be reciprocal to the square ...
The name "saros" (Greek: σάρος) was applied to the eclipse cycle by Edmond Halley in 1686, [7] who took it from the Suda, a Byzantine lexicon of the 11th century. The Suda says, "[The saros is] a measure and a number among Chaldeans. For 120 saroi make 2220 years (years of 12 lunar months) according to the Chaldeans' reckoning, if indeed ...

Raphson was made a Fellow of the Royal Society on 30 November 1689, after being proposed for membership by Edmund Halley. In 1692 he graduated with an M.A. in 1692 from Jesus College which at the time was primarily a training college for Church of England clergy, however as the degree was awarded Royal warrant he probably did not actually study ...
The Orionids meteor shower is produced by Halley's Comet, which was named after the astronomer Edmund Halley and last passed through the inner Solar System in 1986 on its 75–76 year orbit. [10] When the comet passes through the Solar System, the Sun sublimates some of the ice, allowing rock particles to break away from the comet.
In 1705, Edmond Halley (1656–1742) applied Newton's method to 23 cometary apparitions that had occurred between 1337 and 1698. He noted that three of these, the comets of 1531, 1607, and 1682, had very similar orbital elements , and he was further able to account for the slight differences in their orbits in terms of gravitational ...
