In astronomy, a planetary parade, also known as a planetary alignment or planetary procession, occurs when multiple planets in the Solar System are visible at the same time from Earth. However, a planetary parade is not a true alignment in space, but rather an apparent alignment that is the result of the planets' orbital positions relative to viewpoint of Earth-bound observers lying in an arc across the sky.
