Mars vs Naples

Informations

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.

Naples (; Italian: Napoli [ˈnaːpoli] (listen); Neapolitan: Napule [ˈnɑːpələ, ˈnɑːpulə]; Ancient Greek: Νεάπολις, romanized: Neápolis) is a metropolis in Italy. It is the regional capital of Campania and the third-largest city of Italy, after Rome and Milan, with a population of 967,069 within the city's administrative limits as of 2017. Its province-level municipality is the third-most populous metropolitan city in Italy with a population of 3,115,320 residents, and its metropolitan area (that stretches beyond the boundaries of the Metropolitan City of Naples) is the second-most populous metropolitan area in Italy and the 7th-most populous urban area in the European Union. First settled by Greeks in the first millennium BC, Naples is one of the oldest continuously inhabited urban areas in the world. In the ninth century BC, a colony known as Parthenope or Παρθενόπη was established on the Island of Megaride. In the 6th century BC, it was refounded as Neápolis. The city was an important part of Magna Graecia, played a major role in the merging of Greek and Roman society, and was a significant cultural centre under the Romans.It served as the capital of the Duchy of Naples (661–1139), then of the Kingdom of Naples (1282–1816), and finally of the Two Sicilies until the unification of Italy in 1861. Naples is also considered a capital of the Baroque, beginning with the artist Caravaggio's career in the 17th century, and the artistic revolution he inspired. Due to poverty and lack of opportunity, waves of Italians emigrated from Naples in the late 19th and early 20th century, with most going to the United States, where they settled in industrial cities.

Between 1925 and 1936, Naples was expanded and upgraded by Benito Mussolini's government. During the later years of World War II, it sustained severe damage from Allied bombing as they invaded the peninsula. The city received extensive post-1945 reconstruction work.Since the late 20th century, Naples has had significant economic growth, helped by the construction of the Centro Direzionale business district and an advanced transportation network, which includes the Alta Velocità high-speed rail link to Rome and Salerno and an expanded subway network. Naples is the third-largest urban economy in Italy, after Milan and Rome. The Port of Naples is one of the most important in Europe. In addition to commercial activities, it is home to the Allied Joint Force Command Naples, the NATO body that oversees North Africa, the Sahel and Middle East.Naples' historic city centre is the largest in Europe and has been designated as a UNESCO World Heritage Site. A wide range of culturally and historically significant sites are nearby, including the Palace of Caserta and the Roman ruins of Pompeii and Herculaneum. Naples is also known for its natural beauties, such as Posillipo, Phlegraean Fields, Nisida, and Vesuvius. Neapolitan cuisine is noted for its association with pizza, which originated in the city, as well as numerous other local dishes. Naples' restaurants have earned the most stars from the Michelin Guide of any Italian city. The best-known sports team in Naples is the Serie A club S.S.C. Napoli, two-time Italian champions who play football at the San Paolo Stadium in the southwest of the city, in the Fuorigrotta quarter.
