The Brightest Planets in September’s Night Sky: How to See Them (and When)

Eye-popping Venus, low-riding Mercury and stealthy Saturn will all make appearances among the bright objects in September's night sky, and this day-by-day description shows how to find them. This month, Mercury might be glimpsed very low near the west-southwest horizon while Saturn gets lower each evening in the southwest at dusk. Meanwhile Mars, Jupiter and Venus have crossed into the morning sky, but only dazzling Venus is readily seen at dawn as it rapidly rises higher each morning.
