Okay, so I have an astronomy/astrophysics exam tomorrow and I understand everything except for the local standard of rest. Could someone please explain it to me? Thanks!
Don't come here with that crap. I'VE ALREADY USED GOOGLE. I also looked in my textbook and asked my professor about it and I'm still not understanding it, so I came here to ask people who know what they're talking about to see if they can help me.
