On January 21, planetary alignment will bring together Mercury, Venus, Uranus, Mars, Jupiter, and Saturn in a rare celestial display. To get the best view, find a clear, dark spot free from city lights, and look toward the horizon at the time of the alignment. While a perfectly straight line may not be visible, the close grouping of planets will make for an awe-inspiring sight. Be sure to check local conditions and times for optimal viewing.

What is a Planetary Alignment?
A planetary alignment happens when several planets line up on one side of the sun at the same time, according to Starwalk.space. While commonly referred to as a “planetary parade” or “parade of planets,” these terms are not official astronomy terminology, as noted by NASA.
This this celestial phenomenon may look like the planets are lined up from Earth, but the line will rarely be perfectly straight due to the differing speeds at which each planet orbits. The large alignment is a temporary event, and its duration depends on the distance each planet is from the sun.
