The planets, bright stars and dark hours of October–December 2026, plus a live chart for tonight
The season table answers for October–December 2026 in St. Louis's own clock time; the live chart recomputes tonight's Moon, planets and constellations for the city or for your exact location. Both are free and need no sign-up.
Why choose Starry Memory
- Answer first, computed for the city — The season table is calculated for St. Louis's own sky and clock, month by month, rather than copied from a national guide.
- Live for tonight — The chart below recomputes the Moon, planets and constellations for tonight and for your exact location if you allow it.
- Planets and bright stars named — Each month lists which planets are up in the evening, which rise before dawn, and the brightest points you are likely to notice.
- Honest limits — Weather, light pollution and a low horizon are stated, not hidden: a planet above the horizon can still be lost behind cloud or buildings.
The sky over St. Louis changes through the night and through the season. This guide gives the answer for October–December 2026 first; the live chart then shows tonight exactly.

Eclipses in the region
Eclipses listed for the wider region: 20 February 2027: Penumbral lunar eclipse, 23:14 UTC; 17 August 2027: Penumbral lunar eclipse, 07:14 UTC; 12 January 2028: Partial lunar eclipse, 04:14 UTC; 26 January 2028: Annular solar eclipse, 15:08 UTC; 14 January 2029: Partial solar eclipse, 17:13 UTC; 12 June 2029: Partial solar eclipse, 04:06 UTC. A regional match is not a guarantee: solar-eclipse paths are narrow and a lunar eclipse needs the Moon above your horizon. Check the NASA map for each event and never look at the Sun without certified eclipse glasses.
How the times are calculated
Times are local clock times (daylight saving included) for the centre of St. Louis, computed on September 26, 2026 with Astronomy Engine for the 15th of each month. “Evening” means 9 pm, or the end of nautical twilight when it is later; “before dawn” means one hour before sunrise; “full darkness” is the end of astronomical twilight. A flat horizon is assumed: hills, buildings, cloud and light pollution can hide low objects. The live chart at the top of the page recomputes tonight for your exact location.

A night under the St. Louis sky can become a present. The free star map draws the sky of any date and place at 10 pm (the time is set in the poster creator): check the preview before choosing the HD file or a print. To give a star instead, the certificate is a symbolic dedication in a private registry, with a two-page PDF; you can pick one in Pegasus, high over St. Louis in mid-October. Whether a star shows to the naked eye depends on its brightness, the hour and your sky.

In St. Louis time, the full Moons of the season fall on October 25 (11:12 pm), November 24 (8:54 am), December 23 (7:28 pm). The darkest skies, best for faint stars and the Milky Way, are around the new Moons of October 10, November 9, December 8.
Do I need a telescope?
No. Planets and the brightest stars are easy to see with the naked eye once your eyes adapt for 15 to 20 minutes away from direct lights. Binoculars show Jupiter's moons; a small telescope shows Saturn's rings.
Why does the sky change during the year?
The stars rise about four minutes earlier each night, so the evening sky shifts by about two hours a month as the Earth orbits the Sun. From St. Louis, Cygnus and Pegasus are overhead in mid-October; by mid-December, Perseus and Aries have taken over and Gemini is rising in the east. The planets also move against the stars from week to week.
