Harry Edwin Wood
Harry Edwin Wood (3 February 1881 – 27 February 1946) was an English astronomer, director of the Union Observatory in Johannesburg, and discoverer of minor planets. Wood was born in Manchester, graduating from Manchester University in 1902 with first class honours in physics, going on to gain an M.Sc in 1905. In 1906 he was appointed the Chief Assistant at the ''Transvaal Meteorological Observatory'', which soon acquired telescopes and which became known as the Union Observatory and later Republic Observatory. In 1909, he married Mary Ethel Greengrass, also a physics graduate of Manchester University. Wood served as the observatory's director from 1928 to 1941, succeeding Robert Innes. He also served as the president of the ''Astronomical Society of South Africa'' from 1929 to 1930. Wood is credited by the Minor Planet Center with the discovery of 12 numbered asteroids during 1911–1932. He died in Mortimer, near Cradock, Eastern Cape, South Africa, in 1946. The asteroid ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes

Minor Planet Circulars
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC collect ...

1660 Wood
1660 Wood, provisional designation , is a stony Phocaea asteroid from the inner regions of the asteroid belt, approximately 12 kilometers in diameter. It was named after British–South African astronomer Harry Edwin Wood. Discovery ''Wood'' was discovered on 7 April 1953, by South African astronomer Jacobus Bruwer at Johannesburg Observatory in South Africa. It was the second numbered discovery made by Bruwer. He also discovered the minor planets 1658 Innes, 1794 Finsen, and 3284 Niebuhr. The asteroid 1811 Bruwer was named in his honour by the Dutch, Dutch-American astronomer trio of the Palomar–Leiden survey. Orbit and classification ''Wood'' is a S-type asteroid and member of the Phocaea family (). It orbits the Sun in the inner main-belt at a distance of 1.7–3.1  AU once every 3 years and 9 months (1,354 days). Its orbit has an eccentricity of 0.30 and an inclination of 21 ° with respect to the ecliptic. It was first identified as at Lowell Observatory in 1 ...

Cradock, Eastern Cape
Cradock is a town in the Eastern Cape Province of South Africa, in the upper valley of the Great Fish River, by road northeast of Port Elizabeth. The town is the administrative seat of the Inxuba Yethemba Local Municipality in the Chris Hani District of the Eastern Cape. The town is named after John Cradock, governor of the Cape Colony and commander of the forces. Pre-colonial history For thousands of years San hunter-gatherers were the sole human inhabitants of southern Africa. About 2000 years BP the semi-nomadic Khoikhoi (or Khoekhoen or Khoikhoin) arrived with cattle, sheep and goats. These pastoralists migrated south towards the coast. Rock paintings and petroglyphs (engravings) remain as evidence of the first people who lived here. By the 4th century AD Bantu-speaking people had begun to migrate from central Africa down the east coast into southern Africa. The amaXhosa pressed further south to the banks of the Great Fish River where they met San hunter-gatherers and ...

Robert T
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Republic Observatory
Union Observatory also known as Johannesburg Observatory ( 078) is a defunct astronomical observatory in Johannesburg, South Africa that was operated between 1903 and 1971. It is located on Observatory Ridge, the city's highest point at 1,808 metres altitude in the suburb Observatory. The observatory and its former annex, the , are known for the discovery of 6,000 double stars and for Proxima Centauri, made by astronomer Robert Innes. At the observatory, 578 identifications of minor planet were made, a record number at the time. The Minor Planet Center credits the observatory as the site where 147 minor planets were discovered by astronomers Harry Wood, Cyril Jackson, Hendrik van Gent, Ernest Johnson, Ejnar Hertzsprung, Jacobus Bruwer and Joseph Churms ''(see )''. History The origins of the observatory began when Theodore Reunert of the South African Association for the Advancement of Science petitioned Alfred Milner Governor of the Transvaal Colony on 29 October 1902 for ...
