Acronym of AU

( Astronomical Unit ) Single season or cosmic that with the symbols au, and VST. AU or a.u displayed. is the length, and is equal to 149 of 597. the 870/7 km (92 of 955. the 807/27 miles), or almost equal to the distance of the earth to the sun or about 150 million kilometers. The symbol ua on behalf of the Bureau of international weights and measures and the international standard ISO/IEC 80000 offer. while the International Astronomical au to offer. and now, au in English-speaking countries is more typical. In a state, in capital letters, as long as the symbol are used, which after a scientist that the individual worked on is selected. the symbols of au or a.u can means atomic or even a contract. but with the symbol of AU to refer to cosmic nowadays widely used. Fixed cosmic that value equal to one unit Cosmic is the name of The distance can be read, and its symbol A.

the symbol AU on the same principle as the length of a half diameter of orbit the oval-shaped circulation of the earth around the sun, was intended to be. In 1976, the International Astronomical recursive definition AU was and asked that it to be a more accurate expression. The definition was that the AU longitudinal in which the gravitational constant Gauss (k) the amount equal to 0. the 01720209895 there while all the size. cosmic length, mass and time. Define the equivalent of The else that is offered is: the radius of a circular orbit Newtonian, non-turbulent revolves around the Sun, that the particle with the mass of the infinitesimal with the frequency of the angle 0. the 01720209895 Radian on the day of the move it. Or longitudinal that the gravitational constant it is equal to 0. the 017202098952AU3/d2. Approximately is equal to the distance of the earth to the sun.
