Wikipedia: Light on


October 28, 2021


This page is devoted to the organization and maintenance of the Wikipedia: Spotlight on Wikipedia framework. This is completed by calling up the corresponding page, the content of which is updated automatically on a daily basis. When an article is labeled following an AdQ or BA vote, a “Wikipedia: Light on / Name of the labeled article” sub-page must be created. The latter includes the introductory summary of the article (with a maximum of 400 words). The article will then be highlighted on the home page on the scheduled day. There is no "selection", all Wikipedia articles appear on the home page, once labeled. They can also be ironed again after several years, if they have been refurbished by the After Label project. To write a Light on an article, follow the instructions on the help page.

The Kuiper Belt (sometimes referred to as the Edgeworth-Kuiper Belt, pronounced in Dutch: / ˈkœypər /) is an area of ​​the Solar System extending beyond Neptune's orbit, between 30 and 55 astronomical units (AU) . This ring-shaped area is similar to the asteroid belt, but larger, 20 times wider, and 20 to 200 times more massive. Like the asteroid belt, it is mainly composed of small bodies, remnants of the formation of the Solar System, and at least three dwarf planets, Pluto, Makemake and Hauméa (Eris is a scattered object, located beyond the Kuiper belt). In contrast, while the asteroid belt is mostly made up of rocky and metallic bodies, the objects in the Kuiper Belt are mostly made up of frozen volatile compounds like methane, ammonia, or water. Apart from Pluto, spotted in 1930, and its double Charon, detected in 1978, the first Kuiper's object was discovered in 1992. It would be the main reservoir of periodic comets whose period of revolution is less than 200 years. Centaurs and scattered objects, such as Eris, would come from it. Triton, Neptune's largest satellite, could be a Kuiper Belt object that has been captured by the planet. (134340) Pluto is the largest known object in the Kuiper Belt. The Kuiper belt should not be confused with the Oort cloud, an area that is still theoretical and supposed to be a thousand times farther away. The Kuiper Belt objects, as well as the scattered objects and any potential members of the Hills and Oort clouds, are collectively referred to as Transneptunian objects. Read more
