Light Second. It is distance travelled by light in one second `-2.997925 xx 10^(8) m`. Or `792458 km` (`=300,000km` or `186,000` miles) Light year is `9.46` trillion km. One pares `= 3.26` light year or `3.84 xx 10^(13)` km . One astronomical unit (A.U) is `1.496 xx 10^(8)` km or average distance between sun and earth. Light travels this distance in `8.3` minutes.
