Abuja vs Mars

Informations

Abuja () is the capital city of Nigeria situated in the centre of the country within the Federal Capital Territory (FCT). It's a planned city and was built mainly from the 1980s, replacing the nation's most populous city of Lagos as the capital on 12 December 1991. Abuja's geography is characterized by Aso Rock, a 400-metre (1,300 feet ) monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court and much of the city extend into the south of the rock. Zuma Rock, a 792-metre (2,598 feet ) monolith, lies just north of the city on the expressway to Kaduna. At the 2006 census, the city of Abuja had a population of 776,298 which makes it among the ten most populous cities in Nigeria. According to the United Nations, Abuja climbed by 139.7% between 2000 and 2010, which makes it the fastest growing city in the world. As of 2015, the town is experiencing an annual growth of 35%, retaining its position as the weakest city on the African continent and among the fastest-growing in the world.

As of 2016, the metropolitan area of Abuja is estimated at six million individuals, placing it behind only Lagos as the most populous metro area in Nigeria.Major religious websites include the Nigerian National Mosque and the Nigerian National Christian Centre. The town is served by the Nnamdi Azikiwe International Airport. Abuja is known for being among the few purpose-built capital cities in Africa, in addition to being among those wealthiest.Abuja is Nigeria's political and administrative centre. It is also an integral capital on the African continent due to Nigeria's geo-political influence in regional affairs. Abuja is also a conference centre and hosts various meetings annually, like the 2003 Commonwealth Heads of Government meeting and the 2014 World Economic Forum (Africa) meetings.

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.
