I know David Choi asked a question already about the meridian, but I'm still somewhat confused. Just to clarify: Is the meridian basically like the equator that runs north and south instead? Does it go full circle around the celestial sphere? Is this the line that goes through the vernal equinox (which we use to measure right ascension)? Can you also explain that--about the meridian and the vernal equinox? If the meridian is a line, does it also run through the autumnal equinox? Thanks for taking time to answer my questions. I really appreciate it.
