year (a or y or yr) [2]. a traditional unit of time usually equal to 365 or 366 days. We need a whole number of days for the calendar year used in ordinary life. Ancient astronomers knew that the year [1] is approximately 365 days long, and we now know the correct figure is approximately 365.242 days.
A light-year, also light year or lightyear (symbol: ly) is a unit of length, equal to just under 10 trillion kilometers (10Ã1015 meters, 10 petameters or about 6 trillion miles). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year. The light-year is often used to measure distances to stars and other distances on a galactic scale, especially in non-specialist and popular science publications. The preferred unit in astrometry is the parsec, because it can be more easily derived from, and compared with, observational data.
