This distance is equal to 9461 1015 m. After the sun, the star nearest to Earth is Alpha Centauri, which is about 4.35 light-years from Earth. To get a better sense, for instance, of the true distances to exoplanets planets around other stars we might start with the theater in which we find them, the Milky Way galaxy. In those terms, trigonometric calculations based on 61 Cygni's parallax of 0.314 arcseconds, showed the distance to the star to be 660,000 astronomical units (9.91013km; 6.11013mi). Although modern astronomers often prefer to use the parsec, light-years are also popularly used to gauge the expanses of interstellar and intergalactic space. The largest unit for expressing distances across space at that time was the astronomical unit, equal to the radius of the Earth's orbit at 150million kilometres (93million miles). Abstract. In one Earth year of 364.25 days (8,766 hours), light travels a distance of 5,878,625,370,000 miles (9.5 trillion km). [8] The product of Simon Newcomb's J1900.0 mean tropical year of 31556925.9747 ephemeris seconds and a speed of light of 299792.5km/s produced a light-year of 9.4605301015m (rounded to the seven significant digits in the speed of light) found in several modern sources[9][10][11] was probably derived from an old source such as C. W. Allen's 1973 Astrophysical Quantities reference work,[12] which was updated in 2000, including the IAU (1976) value cited above (truncated to 10 significant digits).[13]. Another galaxy, IC 1101, spans as much as 4 million light-years. Are chisel-shaped teeth that are used for biting food?
