Tripoli, Libya
Tripoli (; ar, طرابلس الغرب, translit= Ṭarābulus al-Gharb , translation=Western Tripoli) is the capital and largest city of Libya, with a population of about 1.1 million people in 2019. It is located in the northwest of Libya on the edge of the desert, on a point of rocky land projecting into the Mediterranean Sea and forming a bay. It includes the port of Tripoli and the country's largest commercial and manufacturing center. It is also the site of the University of Tripoli. The vast barracks, which includes the former family estate of Muammar Gaddafi, is also located in the city. Colonel Gaddafi largely ruled the country from his residence in this barracks. Tripoli was founded in the 7th century BC by the Phoenicians, who gave it the Libyco-Berber name ( xpu, 𐤅𐤉‬‬𐤏‬𐤕‬, ) before passing into the hands of the Greek rulers of Cyrenaica as Oea ( grc-gre, Ὀία, ). Due to the city's long history, there are many sites of archeological signi ...

Satellites
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Egyptian Revolution Of 2011
The 2011 Egyptian revolution, also known as the 25 January revolution ( ar, ثورة ٢٥ يناير; ), began on 25 January 2011 and spread across Egypt. The date was set by various youth groups to coincide with the annual Egyptian "Police holiday" as a statement against increasing police brutality during the last few years of Hosni Mubarak's presidency. It consisted of demonstrations, marches, occupations of plazas, non-violent civil resistance, acts of civil disobedience and strike action, strikes. Millions of protesters from a range of socio-economic and religious backgrounds demanded the overthrow of Egyptian President Hosni Mubarak. Violent clashes between security forces and protesters resulted in at least 846 people killed and over 6,000 injured. Protesters retaliated by burning over 90 police stations across the country. The Egyptian protesters' grievances focused on legal and political issues, including police brutality, state-of-emergency laws, lack of political free ...

Near-Earth Object
A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. By convention, a Solar System body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU). If a NEO's orbit crosses the Earth's orbit, and the object is larger than across, it is considered a potentially hazardous object (PHO). Most known PHOs and NEOs are asteroids, but a small fraction are comets. There are over 30,503 known near-Earth asteroids (NEAs) and over a hundred known short-period near-Earth comets (NECs). A number of solar-orbiting meteoroids were large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. Asteroids as small as in diameter can cause significant damage to the local environment and human populations. Larger asteroids penetrate the atmosphere to the surf ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ...
