When was the last planet alignment?
Firstly, there isn’t going to be one in 2012. Now here’re some direct quotes, from University astrophysicists: “Alignment can be used in two different ways for planets. The first way is typically what people first imagine when they hear the phrase planetary alignment, that is, if viewing the solar system from above (i.e., over the Sun’s north pole), the planets form a straight line from the Sun outward. In this scenario as viewed from the Sun, the planet’s would fall on top of one another on the sky (i.e., you would see the planet Mercury and all of the other planets would be hidden behind Mercury). “The second type of alignment is one in which the planets follow a straight line traced out on the sky. Since the bright planets lie in virtually the same plane (i.e., their orbital planes all lie within a few degrees of the Earth’s orbital plane), they will always appear to follow a straight line on the sky if you extend the line far enough. Indeed, we call this “straight line” the eclipti
