N.R. Pogson
Norman Robert Pogson, CIE (23 March 1829 – 23 June 1891) was an English astronomer who worked in India at the Madras observatory. He discovered several minor planets and made observations on comets. He introduced a mathematical scale of stellar magnitudes with the ratio of two successive magnitudes being the fifth root of one hundred (~2.512) and referred to as Pogson's ratio. Youth and education Norman was born in Nottingham, the son of George Owen Pogson, a hosiery manufacturer, lace dealer and commission agent, "with enough income to support an extended family", and his wife, Mary Ann. It was intended that he should follow his father into business, and he was accordingly sent for "commercial education", but he was fascinated by science, and his mother supported and encouraged this interest. His early education was largely informal. He left school at 16, intending to teach mathematics. At the age of eighteen, he calculated with the help of John Russell Hind of the Ro ...

Charles Wood, 1st Viscount Halifax
Charles Wood, 1st Viscount Halifax (20 December 1800 – 8 August 1885), known as Sir Charles Wood, 3rd Baronet, between 1846 and 1866, was a British Whig politician and Member of the British Parliament. He served as Chancellor of the Exchequer from 1846 to 1852. Background Halifax was the son of Sir Francis Lindley Wood, 2nd Baronet of Barnsley, and his wife Anne, daughter of Samuel Buck. He was educated at Eton and Oriel College, Oxford, where he studied classics and mathematics. Political career A Liberal and Member of Parliament from 1826 to 1866, Wood abandoned the seat of Great Grimsby and was returned in 1831 for the pocket borough of Wareham, probably as a paying guest, which arrangement enabled him to remain in London in preparation for the reading of the Reform Bill. He confided his views to his father: the reform is an efficient, substantial, anti-democratic, pro-property measure, but it sweeps away rotten boroughs and of course disgusts their proprietors.

George Airy
Sir George Biddell Airy (; 27 July 18012 January 1892) was an English mathematician and astronomer, and the seventh Astronomer Royal from 1835 to 1881. His many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian. Biography Airy was born at Alnwick, one of a long line of Airys who traced their descent back to a family of the same name residing at Kentmere, in Westmorland, in the 14th century. The branch to which he belonged, having suffered in the English Civil War, moved to Lincolnshire and became farmers. Airy was educated first at elementary schools in Hereford, and afterwards at Colchester Royal Grammar School. An introverted child, Airy gained popularity with his schoolmates through his great skill in the construction of peashooters. From the age of 13, Airy stayed frequen ...

History The history of Oxford in England dates back to its original settlement in the Saxon period. Originally of strategic significance due to its controlling location on the upper reaches of the River Thames at its junction with the River Cherwell, the town grew in national importance during the early Norman period, and in the late 12th century became home to the fledgling University of Oxford. The city was besieged during The Anarchy in 1142. The university rose to dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
245 Vera
Vera (minor planet designation: 245 Vera) is a large Main belt asteroid. It was discovered by N. R. Pogson on February 6, 1885, in Madras, and was named at the suggestion of his wife. The asteroid is orbiting the Sun at a distance of with a period of and an eccentricity (ovalness) of 0.19. The orbital plane is tilted at an angle of 5.16° to the plane of the ecliptic. In 1890, Daniel Kirkwood noted that this asteroid shares similar orbital elements with 86 Semele and 106 Dione. Photometric measurements of this asteroid made during 1980–1981 were used to produce a light curve that demonstrated a rotation period of with a brightness variation of in magnitude. It is classified as a stony S-type asteroid S-type asteroids are asteroids with a spectral type that is indicative of a siliceous (i.e. stony) mineralogical composition, hence the name. They have relatively high density. Approximately 17% of asteroids are of this type, making it the secon ... in the Tholen system. ...

87 Sylvia
Sylvia (minor planet designation: 87 Sylvia) is the one of the largest asteroids (approximately tied for 7th place, to within measurement uncertainties). It is the parent body of the Sylvia family and member of Cybele group located beyond the main asteroid belt (see minor-planet groups). Sylvia was the first asteroid known to possess more than one moon. Discovery and naming Sylvia was discovered by N. R. Pogson on May 16, 1866, from Madras (Chennai), India.Pogson, N. R. (1866), Minor Planet (87) Sylvia', Monthly Notices of the Royal Astronomical Society, Vol. 26, p. 311 (June 1866) Antonio Paluzie-Borrell, writing in Paul Herget's ''The Names of the Minor Planets'' (1955), mistakenly states that the name honors Sylvie Petiaux-Hugo Flammarion, the first wife of astronomer Camille Flammarion. In fact, in the article announcing the discovery of the asteroid, Pogson explained that he selected the name in reference to Rhea Silvia, mother of Romulus and Remus (''MNRAS'', 1866). Phys ...

80 Sappho
Sappho (minor planet designation: 80 Sappho) is a large, S-type (stony) main-belt asteroid. It was discovered by English astronomer Norman Pogson on May 2, 1864, and is named after Sappho, the Archaic Greece poet. The asteroid is orbiting the Sun at a distance of with a period of 3.48 years and an eccentricity (ovalness) of 0.2. The orbital plane is inclined at an angle of 8.68° to the plane of the ecliptic. 13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of . Hanuš et al. (2013) confirmed the polar axis has ecliptic coordinates = and listed a rotation period of 14.03087 h. Sappho (at apparent magnitude 11.8) occulted the magnitude 7.2 star HIP 24403 in the constellation of Taurus on 16 September 2018 at 8:54 UT.

67 Asia
Asia (minor planet designation 67 Asia) is a large main belt asteroid. It was discovered by English astronomer Norman Robert Pogson, N. R. Pogson on April 17, 1861, from the Madras Observatory. Pogson chose the name to refer both to Asia (mythology), Asia, a Titan (mythology), Titaness in Greek mythology, and to the Asia, continent of Asia, because the asteroid was the first to be discovered from that continent. This object is orbiting the Sun with a orbital period, period of , a semimajor axis of , and an orbital eccentricity, eccentricity of 0.185. It has a 2:1 Commensurability (astronomy), commensurability with Mars, having an orbital period double that of the planet. The orbital plane lies at an inclination of 6.0° to the plane of the ecliptic. This is a stony S-type asteroid with a cross-sectional size of 61 km, Photometry (astronomy), Photometry from the Oakley Observatory during 2006 produced a lightcurve that indicated a sidereal rotation period of with an amplitude ...

46 Hestia
Hestia (minor planet designation: 46 Hestia) is a large, dark main-belt asteroid. It is also the primary body of the Hestia clump, a group of asteroids with similar orbits. Hestia was discovered by N. R. Pogson on August 16, 1857, at the Radcliffe Observatory, Oxford. Pogson awarded the honour of naming it to William Henry Smyth, the previous owner of the telescope used for the discovery. Smyth chose to name it after Hestia, Greek goddess of the hearth. This created a problem in Greek, where 4 Vesta also goes by the name ''Hestia''. The computed Lyapunov time for this asteroid is 30,000 years, indicating that it occupies a chaotic orbit that will change randomly over time because of gravitational perturbations of the planets. Hestia has been studied by radar. 13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of 131 km. In 1988 a search for satellites or dust orbiting this asteroid was perfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
