After watching the lesson on Astronomical Distance units (light years, parsecs, AUs), try solving this Challenge Problem: What's the distance to our nearest star, Proxima Centauri, in light years, kilometers, AU, and parsecs? And can you convert from the distance in parsecs to its parallax angle in arc-seconds?
Stay tuned! We'll be adding additional learning resources very soon.
