Seven planets will align in the night sky creating a planetary parade, a rare event that won't happen again until 2040. Some planets are easier to spot than others, with Venus, Jupiter, and Mars visible to the naked eye. Stargazers can use telescopes and apps to help locate the planets.
Key Points
Planetary parades involve multiple planets aligning in the night sky
Seven-planet parades are fairly rare occurrences
Planets in our solar system appear to align due to their orbits around the Sun
Pros
Rare celestial event that occurs only every few years
Opportunity for stargazers to see multiple planets at once
Cons
Some planets like Neptune and Saturn are difficult to spot without special equipment
Limited visibility due to planets' positions near the horizon
