An Incredible 5-planet Parade Is Happening in the Sky This Week — and Won't Be Seen Again Until 2040 - Travel + Leisure

Planets on display include Mercury, Venus, Mars, Jupiter, and Saturn.

The string of planets has dotted the sky all month, but this week promises the best viewing potential.

June 24 will deliver the grandest show: the five planets and a waning crescent moon between Venus and Mars will align in an arc across the sky for roughly a full hour before the sun rises.
