Dates to note
May6
Eta Aquariids peak
May 6, 09:00 UTC; up to 50 (40–80+) meteors an hour under ideal skies (ZHR). Moon 0% lit at the peak. Best from the south. Best time for your city →
May6
New Moon
May 6, 10:58 UTC. The dark-sky window: the best week for faint objects and meteors.
May7
Venus and Saturn 0.6° apart
May 7, around 18h UTC. A close pairing of two planets, 0.6° apart (about 1 Moon-width). Both are 26° or more from the Sun.
May12
The Moon near Jupiter (1.2°)
May 12, around 21h UTC. Closest as seen from Earth's centre; from your location the gap differs by up to about 1°. If that moment falls in your daytime, look the evening before or after.
May13
The Moon near Mars (3.0°)
May 13, around 17h UTC. Closest as seen from Earth's centre; from your location the gap differs by up to about 1°. If that moment falls in your daytime, look the evening before or after.
May13
The Moon near Regulus (1.8°)
May 13, around 18h UTC. Geocentric; from your location the gap differs by up to about 1°.
May17
The Moon near Spica (2.6°)
May 17, around 17h UTC. Geocentric; from your location the gap differs by up to about 1°.
May20
Full Moon
May 20, 10:59 UTC. Flower Moon.
May21
The Moon near Antares (0.1°)
May 21, around 07h UTC. Geocentric; from your location the gap differs by up to about 1°.
May27
Uranus in conjunction with the Sun
May 27, 06:11 UTC. Uranus is behind the Sun and out of sight for a few weeks either side of this date.
May28
Mercury at greatest eastern elongation (23°)
May 28, 10:00 UTC. Mercury is as far from the Sun as it gets on this pass, 23°, in the evening sky after sunset. Mercury is always low in twilight: look low toward the west.
Times in UTC. Separations are geocentric (from Earth's centre). Pairings closer than 3° (planets) or 4° (the Moon and a planet) are listed when the planets are at least 15° from the Sun.
Dates, peaks and ZHR: International Meteor Organization calendar. “Around” marks a peak computed from the solar longitude the IMO lists. Moon: illuminated fraction at the peak.
Space station passes
The ISS and Tiangong orbits are only predictable about six weeks ahead, so pass windows for May 2027 appear here once that month is close. Today's passes: ISS tonight, Tiangong tonight.

Are there meteor showers in May 2027?
Eta Aquariids: peak May 6, 09:00 UTC, ZHR 50 (40–80+).
Computed by us from JPL's DE440 planetary ephemeris with Skyfield: phases, positions, magnitudes (Mallama & Hilton), separations, equinoxes and solstices. Full Moon names are the traditional North American ones. Meteor showers: International Meteor Organization. Eclipses: Fred Espenak, NASA GSFC. Planet times ignore hills and buildings; a planet 5° up needs a clear, low horizon.
