Translational and rotational movements / Movimientos de traslación y rotación

-


The Earth takes 23 hours 56 minutes exactly to turn fully around its axis, which passes through the poles, in west-east direction and in the opposite direction of clockwise. This is called rotation. In addition, this move gives us the feeling that the sky is swirling around our planet.The translational motion is an important movement of the earth, by which our planet moves around the Sun, driven by gravitation, in a time of 365 days, 5 hours and 57 minutes, which is the actual length of the year.The axis of rotation of the Earth is always pointing to an inclined direction. So when in its orbit around the Sun's north pole points toward the Sun, the northern hemisphere receives more heat, while in the Southern hemisphere we get some cold.

Below you'll find a fun and short video that explains everything you need on the subject, I hope you like it.

La Tierra tarda 23 h 56 minutos exactamente en dar una vuelta completa alrededor de su propio eje, que pasa por los polos, en dirección Oeste-Este y en sentido contrario al de las agujas del reloj. A esto se le llama movimiento de rotación. Además con este movimiento da la sensación de que es el cielo el que gira alrededor de nuestro planeta.  

El movimiento de traslación es un importantísimo movimiento de la Tierra, por el cual nuestro planeta se mueve alrededor del Sol impulsado por la gravitación,  en un tiempo de 365 días, 5 horas y 57 minutos, que es la duración real del año.

El eje de rotación de la Tierra está inclinado apuntando siempre a una misma dirección. Por eso, cuando en su vuelta alrededor del Sol el polo norte apunta hacia el Sol, el hemisferio norte recibe más calor, mientras que en el hemisferio sur es epoca de frío.

Aquí tienes un entretenido y corto video que te explica todo lo necesario sobre el tema, espero que os guste.

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

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
