A planetary alignment where all planets are on the same side of the Sun, as shown in the image, is a rare occurrence. Such alignments, called syzygies, are influenced by the different orbital periods of each planet, and though the planets don’t align perfectly in a straight line, a general grouping like this can happen about every 200 years. Complete alignments involving all planets within a limited span of degrees are far rarer and can take even longer to occur, sometimes millennia.
stock here: we had another one of these March 10, 1982, 42 years ago.
