>Syzygy - an alignment of three celestial objects. Word also means any two related things.

Things in general are more powerful than celestial bodies. It takes only two of the former, and as much as three of the latter to create a syzygy.

>>If you look to the west, soon after sunset, you will see what looks as a very bright star - the planet Venus. A little further away from the Sun, there are two other quite bright stars (but much less bright than Venus) - planets Mars, and Saturn. Both are of about the same brightness. Venus is approaching the other two planets, and a few nights from now, they be very close together. An interesting spectacle, to watch night after night, how they approach (and later, how they get away from each other).

>>Jupiter, another very bright planet, can be seen rising in the east, a few hours after sunset.
