Since the middle of the month, four of the five brightest planets in the night sky have been visible after sunset and will continue to "line up" through the end of the month. The best chance to see these four planets and the two hiding in the dark (Neptune and Uranus) will occur around the 21st and 22nd in the southern sky after sunset,

Alignments of five or more planets are rare—there will be two more featuring five or more planets this year, but after that the next won’t happen until 2040.
