A minor planet is an astronomical object in direct orbit around the Sun that is neither a planet nor exclusively classified as a comet . Minor planets can be dwarf planets , asteroids , trojans , centaurs , Kuiper belt objects , and other trans - Neptunian objects . As ___MASK13___ 2016 , the orbits ___MASK13___ 709 , 706 minor planets were archived at the Minor Planet ___MASK27___ , 469 , 275 ___MASK13___ which had received permanent numbers ). ___MASK71___ (" Hallands län ") is a county (" län ") on the western coast ___MASK13___ Sweden . It corresponds roughly to the cultural and historical province ___MASK13___ Halland . The capital is Halmstad . The Kattegat or Kattegatt is a sea area bounded by the Jutlandic peninsula in the ___MASK42___ , the Danish straits islands ___MASK13___ Denmark to the south and the provinces ___MASK13___ Västergötland , Scania , Halland and Bohuslän in Sweden in the east . The Baltic Sea drains into the Kattegat through the Danish Straits . The sea area is a continuation ___MASK13___ the Skagerrak and may be seen as a bay ___MASK13___ the Baltic Sea or the North Sea or , as in traditional Scandinavian usage , neither ___MASK13___ these . The Universe is all ___MASK13___ time and space and its contents . It includes planets , moons , minor planets , stars , galaxies , the contents ___MASK13___ intergalactic space , and all matter and energy . The size ___MASK13___ the entire Universe is unknown . ___MASK88___ (" Kungsbacka kommun ") is a municipality in Halland County on the Swedish west coast , some 30 km south of Gothenburg . The municipal seat is located in the town Kungsbacka . A star is a luminous sphere ___MASK13___ plasma held together by its own gravity . The nearest star to Earth is the Sun . Many other stars are visible to the naked eye from Earth during the night , appearing as a multitude ___MASK13___ fixed luminous points in the sky due to their immense distance from Earth . Historically , the most prominent stars were grouped into constellations and asterisms , the brightest ___MASK13___ which gained proper names . Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations . However , most ___MASK13___ the stars in the Universe , including all stars outside our galaxy , the Milky Way , are invisible to the naked eye from Earth . Indeed , most are invisible from Earth even through the most powerful telescopes . Onsala is a locality situated in ___MASK88___ , Halland County , Sweden , with 11 , 951 inhabitants in 2010 . It is also a 14 km long peninsula on the west coast of Sweden , facing Kattegat , south of Gothenburg . It dates back to the age of the vikings and was originally an area devoted to the god Odin , the name being a corruption of the old norse " Odin ' s Sala ". 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 ___MASK26___ with the naked eye . These were regarded by many early cultures as divine , or as emissaries ___MASK13___ deities . As scientific knowledge advanced , human perception ___MASK13___ the planets changed , incorporating a number ___MASK13___ 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 ___MASK13___ planetary mass based on where or what they orbit . Although eight ___MASK13___ 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 . Onsala Space Observatory ( OSO ) , the Swedish National Facility for Radio Astronomy , provides scientists with equipment to study the ___MASK23___ and the rest ___MASK13___ the Universe . The observatory operates two radio telescopes in Onsala , 45 km south ___MASK13___ Göteborg , and takes part in several international projects . Examples ___MASK13___ activities : The 20 and 25 m telescopes in Onsala : Studies ___MASK13___ the birth and death ___MASK13___ stars , and ___MASK13___ molecules in the Milky Way and other galaxies . LOFAR station : The Swedish station in the international radio telescope LOFAR is located at the observatory . VLBI : Telescopes in different countries are linked together for better resolution ( `` sharper images '' ) . ALMA , e - VLBI , Herschel Space Observatory , SKA : Developing and using new radio astronomical facilities . APEX : Radio telescope in Chile for sub - millimetre waves . Research about everything from planets to the structure ___MASK13___ the Universe . Odin : Satellite for studies ___MASK13___ , e . g . , the ___MASK23___ ' s atmosphere and molecular clouds in the Milky Way . Space geodesy : Radio telescopes ( VLBI ) and satellites ( GPS ) are used to measure movements in ___MASK23___ ' s crust and water vapour in the atmosphere . Receiver development : Laboratories for development ___MASK13___ sensitive radio receivers . Onsala Space Observatory was founded in 1949 by professor Olof Rydbeck . The observatory is hosted by Department ___MASK13___ ___MASK23___ and Space Science at Chalmers University ___MASK13___ Technology , and is operated on behalf ___MASK13___ the Swedish Research Council . ___MASK30___ is the indefinite continued progress ___MASK13___ existence and events that occur in apparently irreversible succession from the past through the present to the future . ___MASK30___ is a component quantity ___MASK13___ various measurements used to sequence events , to compare the duration ___MASK13___ events or the intervals between them , and to quantify rates ___MASK13___ change ___MASK13___ quantities in material reality or in the conscious experience . ___MASK30___ is often referred to as the fourth dimension , along with the three spatial dimensions . In physics , energy is the property that must be transferred to an object in order to perform work on  or to heat  the object , and can be converted in form , but not created or destroyed . The ___MASK91___ unit ___MASK13___ energy is the joule , which is the energy transferred to an object by the mechanical work ___MASK13___ moving it a distance ___MASK13___ 1 metre against a force ___MASK13___ 1 newton . The Moon is an astronomical body that orbits planet ___MASK23___ , being ___MASK23___ ' s only permanent natural satellite . It is the fifth - largest natural satellite in the Solar System , and the largest among planetary satellites relative to the size ___MASK13___ the planet that it orbits ( its primary ). Following Jupiter ' s satellite Io , the Moon is second - densest satellite among those whose densities are known . Space is the boundless three - dimensional extent in which objects and events have relative position and direction . Physical space is often conceived in three linear dimensions , although modern physicists usually consider it , with ___MASK30___ , to be part ___MASK13___ a boundless four - dimensional continuum known as spacetime . The concept ___MASK13___ space is considered to be ___MASK13___ fundamental importance to an understanding ___MASK13___ the physical universe . However , disagreement continues between philosophers over whether it is itself an entity , a relationship between entities , or part ___MASK13___ a conceptual framework . In the classical physics observed in everyday life , if something has mass and takes up space , it is said to be composed ___MASK13___ matter ; this includes atoms ( and thus molecules ) and anything made up ___MASK13___ these , but not other energy phenomena or waves such as light or sound . More generally , however , in ( modern ) physics , matter is not a fundamental concept because a universal definition ___MASK13___ it is elusive : elementary constituents ___MASK13___ atoms may not take up space individually , and massless particles may be composed to form objects that have mass ( even when at rest ). ___MASK36___ , officially the Kingdom ___MASK13___ ___MASK36___ ( Swedish : ), is a Scandinavian country in ___MASK52___ Europe . It borders Norway to the west and Finland to the east , and is connected to Denmark in the southwest by a bridge - tunnel across the Öresund . At , ___MASK36___ is the third - largest country in the European Union by area , with a total population ___MASK13___ 10 . 0 million . ___MASK36___ consequently has a low population density ___MASK13___ , with the highest concentration in the southern half ___MASK13___ the country . Approximately 85 % ___MASK13___ the population lives in urban areas . ___MASK97___ is the second - largest city in Sweden and the fifth - largest in the Nordic countries . Situated by the Kattegat , on the west coast ___MASK13___ Sweden , the city has a population ___MASK13___ approximately 550 , 000 in the urban area and 990 , 000 inhabitants in the metropolitan area . In Germanic mythology , Odin ( from Old Norse Óðinn ) is a widely revered god . In Norse mythology , from which stems ___MASK17___ ___MASK13___ the information about the god , Odin is associated with healing , death , royalty , the gallows , knowledge , battle , sorcery , poetry , frenzy , and the runic alphabet , and is the husband ___MASK13___ the goddess Frigg . In wider Germanic mythology and paganism , Odin was known in Old English as Wden , in Old Saxon as Wdan , and in Old High German as Wuotan or Wtan , all stemming from the reconstructed Proto - Germanic theonym wanaz .
