A transit is an event in which the planet moves directly between the earth and the sun. This means if you look at the sun (with a special filter as to not blind yourself), you can see the planet move across the surface of the sun. This type of event is much rarer than a meteor shower.
Something most people don't know about me is that I have an interest in Astrology. It doesn't control my life, but it does offer insight into the overall energy of the moment, and right now the energy says don't start anything new.
