September 2026 has 2 listed space events. Meteor shower peaks: Southern Taurids Meteor Shower Begins. Moon phases: New Moon September 11 at 03:27 UTC and Full Moon September 26 at 16:49 UTC. Launch dates marked NET are no earlier than and can change.
The full Moon in September 2026 is on September 26 at 16:49 UTC. A full Moon is above the horizon all night and brightens the sky, so faint meteors, the Milky Way and deep-sky objects are harder to see for a few nights around it; the New Moon is the darkest time.
No solar or lunar eclipses occur in September 2026.

Every full moon, eclipse, meteor-shower peak, planetary opposition and elongation, close Moon–planet pairing, equinox, solstice and orbital extreme of 2026. Dates and times are calculated with an astronomical ephemeris and checked by automated tests, not copied from a list. Times are UTC; an event near midnight can fall on the previous or next day where you are.
First full moon of 2026, about 362,300 km away, near perigee and so a supermoon. It rises as the Quadrantids peak.
Peak night of the Quadrantids (radiant in Boötes, parent body Asteroid 2003 EH1), up to about 120 meteors per hour under ideal dark skies. Active 2025-12-26 to 2026-01-16.
Earth is closest to the Sun, about 0.983 AU (147.1 million km).
Jupiter is opposite the Sun, at its brightest and closest to Earth for the year, up all night.
The full moon of early February, traditionally the Snow Moon.
A ring-of-fire annular eclipse whose path crosses Antarctica. Only a partial eclipse is seen from the southern tip of Africa and South America.
Mercury is 18 degrees east of the Sun in the evening sky, a modest apparition because it stays low in the west after sunset.
Mercury, Venus, Saturn and Neptune sit low in the west after sunset while Jupiter and Uranus are high in the east. Only Venus, Mercury and Jupiter are easy to see; Saturn is hard, and Neptune and Uranus need optics.
The Moon moves fully into Earth's shadow and turns deep red. Visible across eastern Asia, Australia, the Pacific and western North America.
The last full moon of northern winter. It falls on the same day as the total lunar eclipse.
Day and night are nearly equal. Spring begins in the Northern Hemisphere and autumn in the Southern.
The first full moon of northern spring.
Mercury reaches 28 degrees west of the Sun, its best morning view of the year in the Northern Hemisphere.
Peak night of the Lyrids (radiant in Lyra, parent body Comet C/1861 G1 (Thatcher)), up to about 18 meteors per hour under ideal dark skies. Active 2026-04-15 to 2026-04-29.
The first of two full moons in May 2026.
Peak night of the Eta Aquariids (radiant in Aquarius, parent body Comet 1P/Halley), up to about 50 meteors per hour under ideal dark skies. Active 2026-04-19 to 2026-05-28.
The second full moon in one calendar month, which is the common meaning of a Blue Moon. The Moon is near its farthest point (about 406,100 km), so it looks slightly smaller.
Mercury is 24.5 degrees east of the Sun in the evening twilight.
A thin crescent Moon passes within 0.3 degrees of Venus in the evening sky.
The longest day in the Northern Hemisphere and the start of summer there; winter begins in the south.
The June full moon. It occurs just before midnight UTC, so on the evening of June 29 in the Americas and June 30 in Asia and Australia.
Earth is farthest from the Sun, about 1.017 AU (152.1 million km).
The July full moon. It washes out the Southern Delta Aquariids at their peak.
Peak night of the Southern Delta Aquariids (radiant in Aquarius, parent body Comet 96P/Machholz), up to about 25 meteors per hour under ideal dark skies. Active 2026-07-18 to 2026-08-21.
Mercury is 19.5 degrees west of the Sun in the morning sky.
Peak night of the Perseids (radiant in Perseus, parent body Comet 109P/Swift-Tuttle), up to about 100 meteors per hour under ideal dark skies. Active 2026-07-14 to 2026-09-01.

Day and night are nearly equal. Autumn begins in the Northern Hemisphere and spring in the Southern. It is still September 22 in the Americas.
Neptune is opposite the Sun and at its best for telescopes. It is too faint to see without optics.
The full moon closest to the September equinox, so the Harvest Moon in 2026.
Saturn is opposite the Sun and at its brightest for the year. The rings are tilted only slightly toward Earth in 2026.
The waning Moon passes within 1.1 degrees of Mars in the morning sky.
The waning Moon passes within 0.3 degrees of Jupiter in the morning sky, close enough that the Moon covers Jupiter from some places.
