Tools for this Unit:

Light Years

A light-year is the distance that light travels in one year. Light travels 186,000 miles a second, which is almost six million million miles, or six trillion miles (6 x 10 1 2). With all those zeros, it would be really easy to make a mistake in reading the distances. So the light year was created to make the numbers more manageable. The chart in Appendix B gives the distance in light years that each star is from the Earth. That distance, combined with the star's intrinsic luminosity determines how bright the star seems to us on Earth.

See Lesson Plan 2 – Les Années-lumières / Light Years.
