Mercury and Venus
When: 21 & 22 May See it with: Naked eye and binoculars How to see it: During evening twilight look towards the northwest horizon about 45 minutes after sunset
Mercury and Venus come together for a stunning conjunction in the early evening of 21 and 22 May. On the 21st the fainter Mercury lies below the dazzling Venus, and the following evening Mercury lies to the left of the brilliant planet so you won’t be able to mix them up. They both fit nicely in the view of 7x50 and 10x50 binoculars and will be very close as seen with the naked eye. Two days later on the 24th, they are joined by the slim crescent Moon, with Mercury forming the apex of a shallow triangle with the Moon and Venus. They set quickly so catch them early in the evening.
