Info about "Light year"

A light-year refers to the distance of light (in a vacuum) within one year. There are different definitions for a year (Gregorian year, tropical year, Julian year etc.), therefore the Julian year (365.25 days) was used as a definition for the light year. A light-year is converted to 9,460,730,472,580.8 km, around 9.5 trillion km. For example, the Milky Way is 100,000 light-years long because distance is difficult to measure in kilometers.

Info about "Light second"

One light-second is defined as the light (in a vacuum) travelled in one second. One light-second is converted to 299,792.458 km, around 300,000 km. For example, the average distance between the earth and the moon is around 1.3 light seconds or about 400,000 kilometers.
