Evening Sky Showcase: Moon Near the Beehive Cluster and Planetary Trio (May 20-21, 2026)
5/22/2026, 4:02:38 AM
Evening Sky Overview
After sunset on May 21, a waxing crescent Moon will sit low in the western sky, less than 5° north-west of the Beehive Cluster (Messier 44, Praesepe). Jupiter will appear about 20° to the Moon’s lower right, while Venus and Mercury form a diagonal line beyond, Mercury barely above the horizon. Pre-dawn, Saturn rises eastward, followed by Mars.
Astronomical Context
The Moon is a 36 % waxing crescent in Cancer. The Beehive Cluster shines at magnitude 3.7 and spans about 95 arcminutes. Jupiter shines brightly; Venus is present alongside Mercury, which stays near the horizon. Saturn’s magnitude is 1.3, making it the brightest pre-dawn object; Mars is slightly fainter. Such a grouping offers a rare chance to view multiple bright planets and a prominent open cluster in a single session.
Viewing Timeline
May 20 evening: Moon in Cancer near M44; Jupiter, Venus, Mercury align westward.
May 21 after sunset: same configuration persists.
Pre-dawn (~4:30 a.m.): Saturn at 10° altitude, Mars at ~1.5°.
Early May 22: Moon sets shortly after midnight.
Key Numbers
Moon–M44 separation < 5°. Moon–Jupiter distance ? 20°. Venus–Mercury diagonal < 5° above horizon for Mercury. Beehive magnitude 3.7, size 95´. Saturn magnitude 1.3, disk 16´´, rings ? 37´´. Mars disk 4´´, magnitude just fainter than Saturn.
Observation Tips
A 10×50 binocular pair (e.g., Nikon Aculon A211) captures the Moon’s terminator and the brightest M44 stars. Small telescopes reveal Theophilus and Piccolomini craters, whose peaks stand out in low-Sun light. For pre-dawn planets, low-power eyepieces help view Saturn’s rings and Titan; Mars appears as a tiny disc near the horizon. Clear western and eastern horizons are essential. A clear western view is required to locate Mercury, which may be lost in the yellow glow of the setting sun.
Conflicts & Gaps
One source reports the Moon-M44 conjunction on May 21 with < 5° offset; another places the Moon near M44 on May 20 with an 8.5° eastward separation. No precise coordinates are given.
