Earth's Distance From Sun

The mean distance from Earth to the Sun, connu sous le nom de the astronomical unit (AU), est défini comme exactement 149,597,870,700 meters (approximativement 149.6 million km or 93 million miles). It serves as the unité fondamentale of distance in solar system astronomy and is utilisé pour exprimer the orbital radii of planets and other solar system bodies. The AU was formally redéfini comme a fixed constant by the International Astronomical Union in 2012. 


mètre

La metre (Commonwealth spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μετρούν, "measure") is the unité de base de longueur dans le Système international d'unités (SI) (SI). The unité SI symbol is m. Le mètre est défini comme the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.

Le mètre was à l'origine defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximativement 40000 km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition a été adopté.
