A new Method of determining the Parallax of the Sun Edmond Halley PHILOSOPHICAL TRANSACTIONS VOL. XXIX (1716) A new Method of determining the Parallax of the Sun, or his Distance from the Earth; by Dr. Halley, Sec. R. S. N0 348, p.454. Translated from the Latin. I W T B S W I B H B AEBD , fig. 3, pl. 5, be described from the centre C , whose semi-diameter let be 31", representing the earth's disk, and in it drawing DabE and cde BCA be the meridian in which the sun is, to which let be inclined the right line FHG C let be 240 such parts as BC is 31; and from C let fall the right line CH perpendicular upon FG . Then supposing the planet in H at 17h55m, or 5h55m in the morning, let the right line FHG CH , that is, 4 minutes. Let the right line KL be also equal to the difference of the apparent semi-diameters of the sun and Venus, or 15' 13½". Then the circle, described with the radius KL , and from any point within the small circle, representing the earth's disk as a centre, will meet the right line FG in the point denoting what o'clock it is at London, when Venus shall touch the sun's limb in an angle of internal contact, in that place of the earth's superficies that lies under the assumed point on the disk. And if a circle, described from the centre C and with the radius KL , meet FG in the points F and G , the right lines FH HG will be = 14' 41", which Venus will appear to pass over in 3h40m.

Edmond Halley (1656 - 1742) The English astronomer and mathematician was the first to calculate the orbit of the comet later named after him. He also played a central role in the publication of Newton's Principia. While at Oxford, Halley was introduced to John Flamsteed, the astronomer royal. The relationship developed and, influenced by Flamsteed's project to compile a catalogue of northern stars, Halley proposed to do the same for the Southern Hemisphere. By the time he returned home in January 1678, he had recorded the celestial longitudes and latitudes of 341 stars and observed a transit of Mercury across the Sun's disk. Halley's star catalogue, published in 1678, was the first to contain telescopically determined locations of southern stars and that year he was elected a fellow of the Royal Society. Along with the inventor and microscopist Robert Hooke, Sir Christopher Wren and Sir Isaac Newton, Halley was trying to develop a mechanical explanation for planetary motion. Although progress had been made, Hooke and Halley were not able to deduce a theoretical orbit that would match the observed planetary motions. However, Newton was already there: the orbit would be an ellipse, and Newton expanded his studies on celestial mechanics in his famous work, the Principia. The Royal Society charged Halley with the business of producing the book, which was published in 1687.

Edmond Halley (October 29, 1656 - January 14, 1742) Edmond Halley was born in Hagerston, Middlesex, England (near London) as son of a wealthy merchant, salter and soapmaker. His birth date is somewhat uncertain because it is not known if at that time in his village the Gregorian or the Julian calendar was in use. There's also some dispute over the year. He got educated at Oxford and studied at Oxford University, Queen's College, 1673-6. He worked with John Flamsteed , the Astronomer Royal in 1675-6 both at Oxford and Greenwich, and observed e.g. the occultation of Mars by the Moon on August 21, 1676. In November 1676, he gave up his studies without final exam, and sailed to St. Helena on the southern hemisphere, in order to compile a catalog of southern stars. The reasons for this are unknown, but it may be that he wanted to complement Flamsteed's mapping of the northern celestial hemisphere on the southern skies. Anyway, he compiled this catalog, the first of the southern skies which he published on his return to England in 1678, and observed the Mercury transit on November 7, 1677. On his return, Halley was elected to the Royal Society on November 30, 1678, and King Charles II graduated him by mandate in 1679. That year, he was sent to Danzig to visit

Halley, Edmond English atronomer who not only identified 1705 the comet that was later to be known by his name, but also compiled a star catalogue, detected the proper motion of stars, using historical records, and began a line of research that - after his death - resulted in a reasonably accurate calculation of the astronomical unit. Halley calculated that the cometary sightings reported in 1456, 1531, 1607, and 1682 all represented reappearances of the same comet. He reasoned that the comet would follow a parabolic path and announced 1705 that it would reappear 1758. When it did, public acclaim for the astronomer was such that his name was irrevocably attached to it. Halley was also a pioneer geophysicist and meteorologist and worked in many other fields, including mathematics. He became the second Astronomer Royal 1720. He was a friend of Isaac Newton, whose Principia he financed. Halley was born near London and studied at Oxford but left without taking a degree. He spent 1676-78 on the S Atlantic island of St Helena, charting the stars of the southern hemisphere. He became professor of geometry at Oxford 1703.

Principal Búsqueda Grupo Galería ... Constelaciones Edmond Halley © 2002. Carlos Andrés Carvajal T. Astrónomo Autodidacta. Nació el 8 de Noviembre de 1656 en Hargerston, Middlesex. Es conocido principalmente por su estudio sobre la periodicidad de los cometas, pero también realizó otras importantes aportaciones como el catálogo de los cielos del sur ( Catalogus stellarum australium , 1678), los métodos para medir la distancia al Sol a través del tránsito de los planetas, el establecimiento del movimiento estelar y la aceleración secular de la Luna. Estudio en Oxford y se convirtió en miembro de la Royal Society a la edad de 22 años. Sus actividades también incluyeron las publicaciones de Apollonius y de otros antiguos geometras como también estudios de matemáticas puras. Es considerado el padre de la Geofísica, estudió el magnetismo de la Tierra y desarrolló una teoría general acerca de el; determinó la ley de los polos magnéticos, la relación entre la presión barométrica y el clima, publicó ensayos sobre óptica y navegación, fue uno de los pioneros en la realización de estadísticas sociales y publicó en 1693 los cálculos anuales de mortalidad en Breslau. Desde la isla de Saint Helena entre 1676 y 1678 catalogó las posiciones de 341 estrellas del hemisferio sur y observó un tránsito de Mercurio a partir de lo cual hipotetizó que estos eventos podrían ser utilizados para determinar la distancia al Sol.
