Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2MASS J11592743-5247188
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torneos y Competencias S.A. (abbreviated TyC, also referred as Torneos) is an Argentine sports communications firm created by businessman Carlos Ávila, associated with Jose Santoro, and Héctor Dayan. It is an important force in the world of Argentine sports, with interests in publications and radio and TV broadcasting. Its headquarters are in Buenos Aires. History Torneos started its activities in the Argentine media in 1982, with a golf program. Since then it produced and aired successful programs in network television such as ''El deporte y el hombre'', ''Tenis de Primera'', ''Fútbol de Primera'' and ''La Magia de la NBA''; the most successful of them being the weekly ''Fútbol de Primera'', which summarizes each day of competition in the Argentine first division. In 1994, Torneos launched the channel TyC Sports to broadcast the Argentine Primera Division.

61 Ursae Majoris
61 Ursae Majoris, abbreviated 61 UMa, is a single star in the northern circumpolar constellation of Ursa Major. It has a yellow-orange hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.35. The distance to this star is 31.2 light years based on parallax, and it is drifting closer with a radial velocity of −5.2 km/s. The star has a relatively high proper motion traversing the sky at the rate of yr−1. The stellar classification of 61 UMa is G8V, matching a late G-type main-sequence star. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. It is considered a solar-type star, having physical properties that make it similar to the Sun. The star has 93% of the mass of the Sun and 86% of the Sun's radius. It is roughly two billion years old and is spinning with a projected rotational velocity of 3.3 km/s, for a period of 17.1 days. The me ...

GJ 3512
GJ 3512 is a nearby star in the northern circumpolar constellation of Ursa Major. It is invisible to the naked eye but can be observed using a telescope, having an apparent visual magnitude of +15.05. The star is located at a distance of 31 light-years from the Sun based on parallax. It has a high proper motion, traversing the celestial sphere at the rate of yr−1. The measurement of the star's radial velocity is poorly constrained, but it appears to be drifting further away at a rate of ~8 km/s. The stellar classification of GJ 3512 is dM5.5, which determines this to be a small red dwarf star that is generating energy through core hydrogen fusion. It displays a moderate amount of magnetic activity with a Sun-like cycle lasting 14 years. A low-level variability lasting matches the approximate rotation period. The star has 12.5% of the mass of the Sun and 16% of the Sun's radius. It is radiating 1.6% of the luminosity of the Sun from its photosphe ...
