But when it comes time to measure distances of heavenly objects, it makes more sense to use the units AU, LY, and PC. That is, Astronomical Units, Light Years, and Parsecs. That’s because space is REALLY big! Today we’ll examine these units that are most commonly used to measure distances in space, and when it makes more sense to use one rather than another. For instance, did you know that astronomical units (AU) are typically used for within our Solar System? But the distance to our nearest star, Proxima Centauri, is so huge that we really do need to jump up to using either Light Years or Parsecs. You'll even hear the terms megaparsec and gigaparsec! ✵✵✵✵✵ CHAPTERS You can jump to chapters in the video here: 0:00 Introduction to AU Astronomical Units 0:33 AU Distances to planets in our Solar System 0:49 Using Light Years (LY) 1:05 LY in km 1:28 Proxima Centauri 1:37 Orion Nebula 1:52 Using Parsecs (PC) 1:57 PC in LY 2:07 Parsec name explanation 2:22 Parallax demonstration 3:23 What is an arc-second 4:15 d = 1/p 5:35 Challenge Question You can check your work on the Challenge Question on our website: https://www.socratica.com/lesson/astronomical-distances-problems ✵✵✵✵✵ THANKS TO OUR SOCRATICA FRIENDS This video was made possible by the generous support of our VIP Patrons on Patreon.
