Asteroids are minor planets, especially those of the inner Solar System.
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter.
An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo (reflectivity).
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.
Álvaro Obregón Salido (February 19, 1880 – July 17, 1928) was a general in the Mexican Revolution, who became President of Mexico from 1920 to 1924.
Centaurs are small solar system bodies with a semi-major axis between those of the outer planets.
A cis-Neptunian object is, literally, any astronomical body found within the orbit of Neptune.
A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing.
D-type asteroids have a very low albedo and a featureless reddish spectrum.
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.
Discovery is the act of detecting something new, or something "old" that had been unrecognized as meaningful.
The term distant minor planet is used by the International Astronomical Union's Minor Planet Center to refer collectively to those minor planets found in the outer Solar System that are not commonly thought of as "asteroids".
Hamburg (locally), Hamborg, officially the Free and Hanseatic City of Hamburg (Freie und Hansestadt Hamburg, Friee un Hansestadt Hamborg),Constitution of Hamburg), is the second-largest city of Germany as well as one of the country's 16 constituent states, with a population of roughly 1.8 million people. The city lies at the core of the Hamburg Metropolitan Region which spreads across four German federal states and is home to more than five million people. The official name reflects Hamburg's history as a member of the medieval Hanseatic League, a free imperial city of the Holy Roman Empire, a city-state and one of the 16 states of Germany. Before the 1871 Unification of Germany, it was a fully sovereign state. Prior to the constitutional changes in 1919 it formed a civic republic headed constitutionally by a class of hereditary grand burghers or Hanseaten. The city has repeatedly been beset by disasters such as the Great Fire of Hamburg, exceptional coastal flooding and military conflicts including World War II bombing raids. Historians remark that the city has managed to recover and emerge wealthier after each catastrophe. Situated on the river Elbe, Hamburg is home to Europe's second-largest port and a broad corporate base. In media, the major regional broadcasting firm NDR, the printing and publishing firm italic and the newspapers italic and italic are based in the city. Hamburg remains an important financial center, the seat of Germany's oldest stock exchange and the world's oldest merchant bank, Berenberg Bank. Media, commercial, logistical, and industrial firms with significant locations in the city include multinationals Airbus, italic, italic, italic, and Unilever. The city is a forum for and has specialists in world economics and international law with such consular and diplomatic missions as the International Tribunal for the Law of the Sea, the EU-LAC Foundation, and the UNESCO Institute for Lifelong Learning. In recent years, the city has played host to multipartite international political conferences and summits such as Europe and China and the G20. Former German Chancellor italic, who governed Germany for eight years, and Angela Merkel, German chancellor since 2005, come from Hamburg. The city is a major international and domestic tourist destination. It ranked 18th in the world for livability in 2016. The Speicherstadt and Kontorhausviertel were declared World Heritage Sites by UNESCO in 2015. Hamburg is a major European science, research, and education hub, with several universities and institutions. Among its most notable cultural venues are the italic and italic concert halls. It gave birth to movements like Hamburger Schule and paved the way for bands including The Beatles. Hamburg is also known for several theatres and a variety of musical shows. St. Pauli's italic is among the best-known European entertainment districts.
Hamburg Observatory (Hamburger Sternwarte) is an astronomical observatory located in the Bergedorf borough of the city of Hamburg in northern Germany.
An hour (symbol: h; also abbreviated hr.) is a unit of time conventionally reckoned as of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions.
Hubble search for transition comets (Transition Comets—UV Search for OH Emissions in Asteroids) was a study involving amateur astronomers and the use of the Hubble Space Telescope.
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in Pasadena, California, United States, with large portions of the campus in La Cañada Flintridge, California.
Julian day is the continuous count of days since the beginning of the Julian Period and is used primarily by astronomers.
In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of SI seconds each.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
In astronomy, a light curve is a graph of light intensity of a celestial object or region, as a function of time.
A Jupiter-crosser is a minor planet whose orbit crosses that of Jupiter.
A Saturn-crosser is a minor planet whose orbit crosses that of Saturn.
The Mexican War of Independence (Guerra de Independencia de México) was an armed conflict, and the culmination of a political and social process which ended the rule of Spain in 1821 in the territory of New Spain.
Mexico (México; Mēxihco), officially called the United Mexican States (Estados Unidos Mexicanos) is a federal republic in the southern portion of North America.
Don Miguel Gregorio Antonio Ignacio Hidalgo-Costilla y Gallaga Mandarte Villaseñor (8 May 1753 – 30 July 1811), more commonly known as Don Miguel Hidalgo y Costilla or simply Miguel Hidalgo, was a Mexican Roman Catholic priest and a leader of the Mexican War of Independence.
Minimum orbit intersection distance (MOID) is a measure used in astronomy to assess potential close approaches and collision risks between astronomical objects.
A minor planet is an astronomical object in direct orbit around the Sun (or more broadly, any star with a planetary system) that is neither a planet nor exclusively classified as a comet.
The Minor Planet Center (MPC) is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids and comets), calculating their orbits and publishing this information via the Minor Planet Circulars.
Neptune is the eighth and farthest known planet from the Sun in the Solar System.
The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect circle.
The perihelion of any orbit of a celestial body about the Sun is the point where the body comes nearest to the Sun.
Pluto (minor planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune.
The President of Mexico (Presidente de México), officially known as the President of the United Mexican States (Presidente de los Estados Unidos Mexicanos), is the head of state and government of Mexico.
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter.
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the widest points of the perimeter.
A solar eclipse (as seen from the planet Earth) is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks ("occults") the Sun.
The Solar SystemCapitalization of the name varies.
Springer Science+Business Media or Springer, part of Springer Nature since 2015, is a global publishing company that publishes books, e-books and peer-reviewed journals in science, humanities, technical and medical (STM) publishing.
A trans-Neptunian object (TNO, also written transneptunian object) is any minor planet in the Solar System that orbits the Sun at a greater average distance (semi-major axis) than Neptune, 30 astronomical units (AU).
Wilhelm Heinrich Walter Baade (March 24, 1893 – June 25, 1960) was a German astronomer who worked in the United States from 1931 to 1959.
