Venus and Mercury are the two nighttime “stars” and meet for a conjuntion, too!
Venus is a dazzlingly gorgeous evening star in the northwest on the 1st, but each night she steadily sinks lower into the dusk until she is gone by month’s end.
Mercury, standing 12 degrees high in fading twilight 40 minutes after sunset in the second half of the month, offers a fine evening apparition.
Venus and Mercury Conjunction (May 21)
Look for Venus and Mercury to make their closest approach to one another on Thursday May 21 after sunset.
As evening darkens, look west, just 10 degrees up from the horizon! Use super-bright Venus to find Mercury, only 1 degree below Venus! (Think of the width of your little finger held at arm’s length.)
Mercury’s brightness may pale compared to Venus’s but the innermost planet is as bright as a 1st-magnitude star. You may see Mercury with the naked eye about 45 minutes to one hour after sunset. Otherwise, use binoculars to identify Venus and you’ll see Mercury in the same field-of-view.
May 22 brings a New Moon so the skies will be dark as our only satellite will cross the sky during the day while the Sun is shining.
Venus and Mercury create a striking dinnertime triangle with the very thin crescent Moon on the 23rd. After their conjunction, Mercury will climb upward day by day while Venus will descend downward. As long as you can catch Venus after sunset, seek for Mercury above Venus.

The three morning planets this month are Jupiter, Saturn and Mars – which are easy to spot from the waning Moon from May 12 to 14, 2020.
On May 12, at about 4.00 a.m., look for the Moon in the sky, then find both Jupiter and Saturn just above the Moon. Jupiter is by far the brightest of the two. Nearby is the ringed planet Saturn.
Watch the Moon move towards Mars on the 13th, ending below and slightly to the right of steadily brightening Mars on the 14th.
