MoonThe Moon is Earth's only natural satellite. Its diameter is about one-quarter of Earth's (comparable to the width of Australia), making it the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet. It is larger than all known dwarf planets in the Solar System. The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term. It lacks any significant atmosphere, hydrosphere, or magnetic field.
Full moonThe full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic longitudes of the Sun and Moon differ by 180°). This means that the lunar hemisphere facing Earth—the near side—is completely sunlit and appears as an approximately circular disk. The full moon occurs roughly once a month. The time interval between a full moon and the next repetition of the same phase, a synodic month, averages about 29.
Moon landingA Moon landing or lunar landing is the arrival of a spacecraft on the surface of the Moon. This includes both crewed and robotic missions. The first human-made object to touch the Moon was the Soviet Union's Luna 2, on 13 September 1959. The United States' Apollo 11 was the first crewed mission to land on the Moon, on 20 July 1969. There were six crewed U.S. landings between 1969 and 1972, and numerous uncrewed landings, with no soft landings happening between 22 August 1976 and 14 December 2013.
Colonization of the MoonColonization of the Moon is a process or concept employed by some proposals for robotic or human exploitation and settlement endeavours on the Moon. Settling of the Moon is therefore a more specific concept, for which the broader concept of colonization is often used as a synonym, a use that is contested in the light of colonialism. Laying claim to the Moon has been declared illegal through international space law and no state has made such claims, despite having a range of probes and artificial remains on the Moon.
Orbit of the MoonThe Moon orbits Earth in the prograde direction and completes one revolution relative to the Vernal Equinox and the stars in about 27.32 days (a tropical month and sidereal month) and one revolution relative to the Sun in about 29.53 days (a synodic month). Earth and the Moon orbit about their barycentre (common centre of mass), which lies about from Earth's centre (about 73% of its radius), forming a satellite system called the Earth–Moon system. On average, the distance to the Moon is about from Earth's centre, which corresponds to about 60 Earth radii or 1.
ExhibitionAn exhibition, in the most general sense, is an organized presentation and display of a selection of items. In practice, exhibitions usually occur within a cultural or educational setting such as a museum, art gallery, park, library, exhibition hall, or World's fairs. Exhibitions can include many things such as art in both major museums and smaller galleries, interpretive exhibitions, natural history museums and history museums, and also varieties such as more commercially focused exhibitions and trade fairs.
SovereigntySovereignty can generally be defined as supreme authority. Sovereignty entails hierarchy within the state, as well as external autonomy for states. In any state, sovereignty is assigned to the person, body or institution that has the ultimate authority over other people in order to establish a law or change existing laws. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. In international law, sovereignty is the exercise of power by a state.
Popular sovereigntyPopular sovereignty is the principle that the authority of a state and its government are created and sustained by the consent of its people, who are the source of all political power. Popular sovereignty, being a principle, does not imply any particular political implementation. Benjamin Franklin expressed the concept when he wrote that "In free governments, the rulers are the servants and the people their superiors and sovereigns".
Art exhibitionAn art exhibition is traditionally the space in which art objects (in the most general sense) meet an audience. The exhibit is universally understood to be for some temporary period unless, as is occasionally true, it is stated to be a "permanent exhibition". In American English, they may be called "exhibit", "exposition" (the French word) or "show". In UK English, they are always called "exhibitions" or "shows", and an individual item in the show is an "exhibit".
MuseumA museum (mjuːˈziːəm ) is a community service that displays and preserves objects of significance. Many museums have exhibitions of these objects in public display, and some have private collections that are used by researchers and specialists. Compared to a library, a museum hosts a much wider ranges of objects and usually focus around a specific theme such as the arts, science, natural history, local history, and other topics.
Self-ownershipSelf-ownership, is the concept of property in one's own body, expressed as the moral or natural right of a person to have bodily integrity which means to be the exclusive controller of one's own body including one's life, where 'control' means exerting any physical interference and 'exclusive' means having the right to install and enforce a ban on other people doing this. Since the legal norm of property title claim incapacitates (or bans) other people (except the zygote) from claiming property title over the same resource at the same time, the right to control or interfere with one's own body in any arbitrary way is secured.
