Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
Attometer
An attometer is a unit of length in the metric system equal to 10^-18 meters.
History/Origin
The prefix "atto-" for 10^-18 was adopted by the CGPM (General Conference on Weights and Measures) in 1964.
Current Use
The attometer is used in high-energy physics to describe the scales relevant to quarks and leptons.
