Outer Solar System Origins Survey
The Outer Solar System Origins Survey (OSSOS) is an astronomical survey and observing program aimed at discovering and tracking trans-Neptunian objects located in the outermost regions of the Solar System beyond the orbit of Neptune. OSSOS is designed in way that observational biases can be characterized, allowing the numbers and orbits of detected objects to be compared using a survey simulator to the populations predicted in dynamical simulations of the emplacement of trans-Neptunian objects. Conducted at the Canada-France-Hawaii telescope at Mauna Kea Observatories in Hawaii, the survey has discovered 39 numbered objects as of 2018, with potentially hundreds more to follow. The survey's first numbered discovery was the object in 2013. Description OSSOS observed eight blocks of the sky over a period of five years from 2013–2017 using the MegaPrime camera of the 3.6-meter Canada-France-Hawaii Telescope. Images of these blocks were taken near opposition (when the block is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 International Astronomical Union, August 24, 2006.

Astronomical Surveys
An astronomical survey is a general map or image of a region of the sky (or of the whole sky) that lacks a specific observational target. Alternatively, an astronomical survey may comprise a set of images, spectra, or other observations of objects that share a common type or feature. Surveys are often restricted to one band of the electromagnetic spectrum due to instrumental limitations, although multiwavelength surveys can be made by using multiple detectors, each sensitive to a different bandwidth. Surveys have generally been performed as part of the production of an astronomical catalog. They may also search for transient astronomical events. They often use wide-field astrographs. Scientific value Sky surveys, unlike targeted observation of a specific object, allow astronomers to catalog celestial objects and perform statistical analyses on them without complex corrections for selection effects. In some cases, an astronomer interested in a particular object will find tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Trans-Neptunian Objects
This is a list of trans-Neptunian objects (TNOs), which are minor planets in the Solar System that orbit the Sun at a greater distance on average than Neptune, that is, their orbit has a semi-major axis greater than 30.1 astronomical units (AU). The Kuiper belt, scattered disk, and Oort cloud are three conventional divisions of this volume of space. , the List of minor planets#Main index, catalog of minor planets contains #List, 901 numbered TNOs. In addition, there are more than List of unnumbered trans-Neptunian objects, 3,000 unnumbered TNOs, which have been observed since 1993. This list consists of all types of TNO subgroups: classical Kuiper belt objects, also known as "cubewanos", the resonant trans-Neptunian objects with their Resonant trans-Neptunian object#2:3, main and Resonant trans-Neptunian object#Other resonances, higher-order resonant subgroups, the scattered disc objects (SDOs), and the extreme trans-Neptunian objects including the Extreme scattered disc object, ...

Scott Tremaine
Scott Duncan Tremaine (born 1950) is a Canadian-born astrophysicist. He is a fellow of the Royal Society of London, the Royal Society of Canada and the National Academy of Sciences. Tremaine is widely regarded as one of the world's leading astrophysicists for his contributions to the theory of Solar System and galactic dynamics. Tremaine is the namesake of asteroid 3806 Tremaine. He is credited with coining the name " Kuiper belt". Career He obtained a bachelor's degree at McMaster University in 1971, and a PhD from Princeton University in 1975. He further received an honorary PhD from McMaster University in 1996. He was an associate professor at the Massachusetts Institute of Technology from 1981 to 1985. He became the first director of the Canadian Institute for Theoretical Astrophysics at the University of Toronto in 1986, a position he held until 1996. He gained the rare distinction of "University Professor" at the University of Toronto in 1995. In 1997, he left CITA and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megan Schwamb
Megan E. Schwamb (born 1984) is an American astronomer and planetary scientist, and lecturer at Queen's University, Belfast. Schwamb has discovered and co-discovered several trans-Neptunian objects, and is involved with Citizen science projects such as Planet Four and Planet Hunters. Biography In 2006, Schwamb graduated from the University of Pennsylvania with a B.A summa cum laude with Distinction in physics.
