Well I'm not a big proponent of astrology, I mean a lot of its projections sound like a pseudoscience. Its not something that is totally impossible though. Planetary alignment HAS to have some effect(even if it is a small one) on a person's development. Everything kind of puts its print on everything. If I were to drop a small piece of dirt on the ground, that dirt would affect everything. The air would an extremely slight shift, everything would change ever so slightly. Gravitational forces would shift somewhat. Even behavioral pattens would change.
