Amman vs Mars

Informations

Amman (English:; Arabic: عَمّان‎ ʻammān pronounced [ʕamːaːn]) is the capital and largest city of Jordan and the country's economic, cultural and political centre. With a population of 4,007,526, Amman is the biggest city in the Levant area and the sixth-largest town in the Arab world.The earliest evidence of settlement in Amman is in a Neolithic site known as'Ain Ghazal, where some of the oldest human statues ever discovered dating to 7250 BC were uncovered. During the Iron Age, the city was known as Ammon, home to the Kingdom of the Ammonites. It was called Philadelphia during its Greek and Roman periods, and was finally called Amman during the Islamic period. For much of the middle and early Islamic periods (7th--14th centuries), it served as a centre for the Balqa district of Syria. Afterwards, Amman was a largely abandoned site before the late 19th century when Circassian immigrants were settled there by the Ottoman Empire in 1878. The first municipal council was established in 1909. Amman witnessed rapid growth after its designation as Transjordan's capital in 1921, and after several successive waves of refugees: Palestinians in 1948 and 1967; Iraqis in 1990 and 2003; and Syrians since 2011. It was originally built on seven hills but now spans over 19 hills combining 22 areas, which are administered by the Greater Amman Municipality headed by its mayor Yousef Shawarbeh.

Areas of Amman have gained their titles from either the hills (Jabal) or the valleys (Wadi) they occupy, such as Jabal Lweibdeh and Wadi Abdoun. East Amman is predominantly filled with historical sites that frequently host cultural activities, while West Amman is more modern and serves as the financial centre of the city.Approximately two million visitors arrived in Amman in 2014, which made it the 93rd most visited city in the world and the 5th most visited Arab city. Amman has a relatively fast growing market, and it is ranked as a Beta− worldwide city by the Globalization and World Cities Research Network. In addition, it was named among the Middle East and North Africa's finest cities based on economic, labour, environmental, and socio-cultural factors. The city is one of the most popular locations in the Arab world for multinational corporations to establish their regional offices, together with Doha and just behind Dubai. It is expected that in the next 10 years these three towns will capture the largest share of multinational corporation activity in the area.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet". The latter refers to the effect of the iron oxide prevalent on Mars's surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, with surface features reminiscent of the impact craters of the Moon and the valleys, deserts and polar ice caps of Earth. The days and seasons are comparable to those of Earth, because the rotational period as well as the tilt of the rotational axis relative to the ecliptic plane are similar. Mars is the site of Olympus Mons, the largest volcano and highest known mountain on any planet in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.Mars has been explored by several uncrewed spacecraft. Mariner 4 was the first spacecraft to visit Mars; launched by NASA on 28 November 1964, it made its closest approach to the planet on 15 July 1965. Mariner 4 detected the weak Martian radiation belt, measured at about 0.1% that of Earth, and captured the first images of another planet from deep space. The Soviet Mars 3 mission included a lander, which achieved a soft landing in December 1971; however, contact was lost seconds after touchdown. On 20 July 1976, Viking 1 performed the first successful landing on the Martian surface. On 4 July 1997, the Mars Pathfinder spacecraft landed on Mars and on 5 July released its rover, Sojourner, the first robotic rover to operate on Mars.

The Mars Express orbiter, the first European Space Agency (ESA) spacecraft to visit Mars, arrived in orbit on 25 December 2003. In January 2004, the Mars Exploration Rovers, named Spirit and Opportunity, both landed on Mars. Spirit operated until 22 March 2010 and Opportunity lasted until 10 June 2018. On 24 September 2014, the Indian Space Research Organisation (ISRO) became the fourth space agency to visit Mars when its maiden interplanetary mission, the Mars Orbiter Mission spacecraft, arrived in orbit.There are investigations assessing the past habitability of Mars, as well as the possibility of extant life. Astrobiology missions are planned, including the Perseverance and Rosalind Franklin rovers. Liquid water on the surface of Mars cannot exist due to low atmospheric pressure, which is less than 1% of the atmospheric pressure on Earth, except at the lowest elevations for short periods. The two polar ice caps appear to be made largely of water. The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the planetary surface to a depth of 11 metres (36 ft). In November 2016, NASA reported finding a large amount of underground ice in the Utopia Planitia region. The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior.Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude reaches −2.94, which is surpassed only by Venus, the Moon and the Sun. Optical ground-based telescopes are typically limited to resolving features about 300 kilometres (190 mi) across when Earth and Mars are closest because of Earth's atmosphere.
