Hey, Dr. Science-Patterson! What exactly is the vernal equinox? - Quizzical in Camarillo

Dear Quizzical in Camarillo: This is a question you should already know the answer to. But, okay…Let’s use an analogy to explain it. Pretend that, say, a penny is the Earth. The vernal equinox is when the Sun, which moves along the Eliptic, occupies the point that crosses the Equator while heading north. (You can use something to represent the Eliptic.)
