Mars, Jupiter, Uranus, Venus, Neptune, Mercury and Saturn will appear in a row on the evening of 28 February, marking the last time for 15 years that all of the planets will be visible at the same time. Planetary parades of four or five planets happen relatively regularly, though alignments of six or seven are remarkably rare.

Though the planets are always “aligned,” seeing more than four in the sky is more uncommon. February’s lineup is a chance to glimpse all seven in one sweeping view.

According to Star Walk, "the next time seven planets will align (after Feb. 28, 2025) is likely to be around late 2028." "An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said.
