Mars / Marte

-

Mars is also called the Red Planet and is the fourth planet from the Sun. It is part of the so-called rocky planets like Earth and is in many aspects the planet most alike the Earth. The atmosphere of Mars is a hundredth of the one of the Earth and its composition is essentially: carbon dioxide in a high percentage with some nitrogen, argon and molecular oxygen. The ozone content is 1000 times lower than the Earth, so that the layer is unable to block ultraviolet radiation. Its atmosphere is dense enough to hold strong winds and vast dust storms that can eventually encompass the entire planet for months creating sand dunes, common renderings in Martian deserts. Mars has two small moons, whose orbit is very close to the planet, Phobos and Deimos. It takes 687 days to orbit around the sun. Its diameter is 6780 km.

Marte es también llamado el Planeta Rojo y es el cuarto planeta del Sistema Solar. Forma parte de los llamados planetas rocosos como la Tierra y es en muchos aspectos el planeta más parecido a la Tierra. La atmósfera de Marte representa una centésima parte de la terrestre y su composición es fundamentalmente: dióxido de carbono en un altísimo porcentaje junto a un poco de nitrógeno, argón y oxígeno molecular. El contenido de ozono es 1000 veces menor que en la Tierra, por lo que su capa  es incapaz de bloquear la radiación ultravioleta. Su atmósfera es lo bastante densa como para albergar fuertes vientos y grandes tormentas de polvo que pueden llegar a abarcar el planeta entero durante meses y deviniendo en dunas de arena habituales en  los desiertos marcianos. Marte posee dos pequeños satélites naturales, cuya órbita está muy próxima al planeta, Fobos y Deimos. Tarda 687 días en dar la vuelta alrededor del sol. Su diámetro es 6780 km.

Eris, Makemake and Haumea / Eris, Makemake y Haumea

Eris, Makemake and Haumea are dwarf planets located behind Pluto, in areas of the solar system known as scattered disk and Kuiper Belt. They are known as dwarf planets likewise Ceres and Pluto, but unlike these two have not been seen in sufficient detail to show that completely fit the definition of planets. Eris has a mass larger than Pluto and Makemake and Haumea are still under investigation. Besides these three bodies fall into a new category called "plutinos" or "trans-" by many. Although the IAU does not specify a specific name, are often referred to by the abbreviation TNO (Trans neptunian object). This category of objects similar to Pluto only applies to dwarf planets if they are trans-Neptunian objects and their periods, inclinations and eccentricity are similar to those of Pluto and therefore are on the scattered Disk, the Kuiper Belt or the Oort Cloud. In addition, there are a few bodies who are candidates for recognition as "dwarf planets" ...

Uranus / Urano

-
Imagen
Uranus is the seventh planet from the Sun and the third largest. The main feature of Uranus is the inclination of its axis almost ninety degrees with respect to its orbit, an inclination which is not only limited to the same planet, but its rings, satellites and magnetic field. Uranus has the most uniform surface of all the planets by their characteristic blue-green color produced by the combination of gases in its atmosphere. Although at first glance it may not seem, it has a system of rings, including one blue. It is also a gaseous planet. As happens with Venus, Uranus has a retrograde motion, turning clockwise. The planet has an atmosphere formed by a mixture of hydrogen and helium and traces of methane (being about 15% of its planetary mass) and the mantle would be formed by ice and chemical oceans, water, ammonia and methane, providing a high electrical conductivity. Uranus has 27 known moons, Titania and Oberon being the largest with a similar size (1580 and 1520 km in diameter...
