- Mars (Wikipedia)
Mars is the fourth planet and the furthest terrestrial planet from the Sun. The reddish color of its surface is due to finely grained iron(III) oxide dust in the soil, giving it the nickname “the Red Planet”. Mars’s radius is second smallest among the planets in the Solar System at 3,389.5 km (2,106 mi). It has a surface gravity of 3.72 m/s2 (12.2 ft/s2), which is 38% of Earth’s gravity. The Martian dichotomy is visible on the surface: on average, the terrain on Mars’s northern hemisphere is flatter and lower than its southern hemisphere. Mars has a thin atmosphere made primarily of carbon dioxide and two irregularly shaped natural satellites: Phobos and Deimos.

Fidel Alejandro Castro Ruz (/ˈkæstroʊ/ KASS-troh, Latin American Spanish: [fiˈðel aleˈxandɾo ˈkastɾo ˈrus]; 13 August 1926 – 25 November 2016) was a Cuban revolutionary and politician who was the leader of Cuba from 1959 to 2008, serving as the prime minister of Cuba from 1959 to 1976 and president from 1976 to 2008. Ideologically a Marxist–Leninist and Cuban nationalist, he also served as the first secretary of the Communist Party of Cuba from 1965 until 2011. Under his administration, Cuba became a one-party communist state; industry and business were nationalized, and socialist reforms were implemented throughout society.
