A 7-planet alignment will be visible in Michigan skies on Friday. Here's what to know and how to see the planetary alignment.

All it requires is their orbits bringing them to the same side of the Sun as the Earth. But it's remarkably rare for six planets to align, and even rarer for seven. Only five planets, Mars ...
