He has received a handful of awards including the Danish Tycho Brahe Medal . - A planet is an astronomical body orbiting a star or stellar remnant that The term "planet" is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such. - An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside of the scope of Earth. They look at stars, planets, moons, comets and galaxies, as well as many other celestial objects either in observational astronomy, in analyzing the data or in theoretical astronomy. Examples of topics or fields astronomers work on include: planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. There are also related but distinct subjects like physical cosmology which studies the Universe as a whole. - The International Astronomical Union (IAU UAI) is an international association of professional astronomers, at the PhD level and beyond, active in professional research and education in astronomy. Among other activities, it acts as the internationally recognized authority for assigning designations to celestial bodies (stars, planets, asteroids, etc.) and any surface features on them. - Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.

There were twelve prime ministers of North Yemen . - Yemen ('), officially known as the Republic of Yemen ('), is an Arab country in Western Asia, occupying South Arabia, the southern end of the Arabian Peninsula. Yemen is the second-largest country in the peninsula, occupying 527,970km (203,850sqmi). The coastline stretches for about 2,000km (1,200mi). It is bordered by Saudi Arabia to the north, the Red Sea to the west, the Gulf of Aden and Arabian Sea to the south, and Oman to the east-northeast. Although Yemen's constitutionally stated capital is the city of Sana'a, the city has been under rebel control since February 2015. Because of this, Yemen's capital has been temporarily relocated to the port city of Aden, on the southern coast. Yemen's territory includes more than 200 islands; the largest of these is Socotra. - Socotra ('), also spelled Soqotra, is an island and a small archipelago of four islands in the Arabian Sea. The territory is part of Yemen, and had long been a subdivision of the Aden Governorate. In 2004, it became attached to the Hadhramaut Governorate, which is much closer to the island than Aden (although the nearest governorate was the Al Mahrah Governorate). In 2013, the archipelago became its own governorate, the Soqatra Governorate. - Sana'a (also spelled Sanaa or Sana; "" ) is the largest city in Yemen and the centre of Sana'a Governorate. The city is not part of the Governorate, but forms the separate administrative district of "Amanat Al-Asemah". Under the Yemeni constitution, Sana'a is the capital of the country, although the seat of the internationally recognised government moved to Aden in the aftermath of the 201415 Yemeni coup d'etat. Aden was declared as the temporary capital by President Abd Rabbuh Mansur Hadi in March 2015. - The People's Democratic Republic of Yemen ('), also referred to as South Yemen, Democratic Yemen or Yemen (Aden) a.k.a. South Arabian Federation, was a socialist state in the southern and eastern provinces of the present-day Republic of Yemen, including the island of Socotra. It united with the Yemen Arab Republic (commonly known as "North Yemen") on 22 May 1990, to form the present-day Yemen. After four years, however, South Yemen declared its secession from the north, which resulted in the north occupying south Yemen and the 1994 civil war. - The Red Sea (also the Erythraean Sea) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. To the north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). The Red Sea is a Global 200 ecoregion. The sea is underlain by the Red Sea Rift which is part of the Great Rift Valley. - The Yemen Arab Republic (YAR; '), also known as North Yemen or Yemen (Sana'a)"', was a country from 1962 to 1990 in the northwestern part of what is now Yemen. Its capital was at Sana'a. It united with the People's Democratic Republic of Yemen, commonly known as South Yemen, on May 22, 1990, to form the current Republic of Yemen.
