Visible planets and night sky for October

October 8 – 10 morning conjunctions: Moon, Beehive, Venus, Regulus

The waning moon sweep past the famous Beehive star cluster on the morning of October 8, 2023. You’ll need binoculars to spot the dozens of stars in the busy Beehive star cluster. On October 9, the moon will appear above brilliant Venus and the bright star Regulus, Heart of the Lion in star in Leo. The Venus-Regulus conjunction will take place on the morning of October 10, when the moon is nearby. Don’t miss it!

October 8 and 9 evenings: Draconid meteor shower

Watch for the short-lived Draconid meteor shower at nightfall and early evening on October 8, 2023. The expected peak is in the early morning of October 9, according to American clocks. So you might watch the evening of October 9, too. Just be aware that the Draconid meteor shower is a real oddity, in that its radiant point will be highest in the sky as darkness falls. That’s why you’ll see more Draconids in the evening hours than in the morning hours after midnight. This chart faces northward at nightfall in October. The meteors radiate from what are known as the Dragon’s Eyes – the stars Eltanin and Rastaban – in the constellation Draco. Do you need to find the radiant point to enjoy the shower? Not at all. Just go to a dark sky on the evenings of October 8 and 9, and look up! Read more about the Draconid meteor shower.

Moon at apogee around October 10

The moon will reach apogee – its farthest distance from Earth in its elliptical orbit – at 4 UTC on October 10, 2023 (11 p.m. CDT on October 9), when it’s 251,919 miles (405,425 km) away.

October 12 and 13 mornings: Waning moon and Venus

On the mornings of October 12 and 13, 2023, the thin waning crescent moon will lie just above the horizon in the eastern morning twilight before sunrise. Brilliant Venus and the bright star Regulus will be higher in the sky. On both mornings, the unlit portion of the moon will exhibit the lovely glow of earthshine, which is reflected light from Earth.

First of 2 great American eclipses on October 14

The instant of new moon falls at 17:55 UTC (12:55 p.m. CDT) on October 14, 2023. And, that day, the first of two great American solar eclipses will take place. Only those using proper eye protection – in a narrow swath sweeping over North and South America – will get to see the sun form a ring around the moon at mid-eclipse. But many more will observe a partial solar eclipse. Make sure you protect your eyes with eclipse glasses throughout this eclipse. Find maps and more about the annular solar eclipse on October 14.

Ways to watch a solar eclipse safely on October 14

The time is now to get ready for the annular solar eclipse on October 14, 2023, visible over the Americas. Also, the sun’s Solar Cycle 25 is ramping up, and there is going to be an increasing number of spots on the sun in the coming years. Watch this video for tips on observing the solar eclipse and the sun safely.

2nd and 3rd weeks of October: Watch for the zodiacal light

The weeks around the September equinox are the best time to see a hazy pyramid of light in the sunrise (Northern Hemisphere) or sunset (Southern Hemisphere) direction. Watch for this light – called the zodiacal light – before dawn breaks in the north, or when all traces of evening twilight have left the sky in the south. Read more here, or watch the video below.

October 16 and 17 evenings: Crescent moon reappears in the evening

On the evenings of October 16 and 17, 2023, the thin waxing crescent moon will hang in the evening twilight near the horizon shortly after sunset. The bright fiery red star Antares will lie near the moon. Can you see any of the constellation of Scorpius – other than Antares – in the bright twilight? Also, on both evenings, look for the subtle glow of earthshine. Earthshine is the dim glow on the darkened portion of a crescent moon. It’s light from Earth shining on the night side of the moon.

October 18 evening: Moon close to Antares

On the evening of October 18, 2023, the thin waxing crescent moon will float close to the bright red star Antares. It’s the brightest star in the constellation of Scorpius the Scorpion. The subtle illumination on the unlit side of the moon is earthshine. Its glow is light reflected from the Earth enabling us to see the dark side of the moon.

October 19 and 20 evenings: Moon near the Teapot

The thickening waxing crescent moon will pass the Teapot – an asterism – of Sagittarius the Archer on the evenings of October 19 and 20, 2023. On the second evening, the moon will float in front of the Teapot. By the way, the spout of the Teapot points to the center of our Milky Way galaxy.

October 21 and 22 evenings: Moon near Capricornus

The 1st quarter moon will pass the constellation Capricornus the Sea-goat on the evenings of October 21 and 22, 2023. Under dark skies, the constellation has the distinct shape of an arrowhead. The moon and Capricornus will be visible as darkness falls and set around midnight.

October 21 evening: 1st quarter moon

The instant of 1st quarter moon falls at 3:29 UTC on October 22, 2023, (10:29 p.m. CDT on October 21).

October 22 morning: Orionid meteor shower

The predicted peak of the Orionid meteor shower is the morning of October 22, 2023.

October 23 morning: Venus greatest distance from the sun

Venus will reach greatest elongation – at 46 degrees – from the sun at 23 UTC (6 p.m. CDT) on October 23, 2023.

October 23 and 24 evenings: Moon near Saturn

The waxing gibbous moon will pass the steady light of golden Saturn on the evenings of October 23 and 24, 2023. The Water Jar asterism of the constellation Aquarius the Water Bearer will shine nearby. You’ll be able to watch Saturn and the moon until they set after midnight.

October 25 and 26 evenings: Moon near the Great Square

The waxing gibbous moon will glow brightly below the asterism of the Great Square of Pegasus on the evenings of October 25 and 26, 2023. You can find the moon and the Great Square until a few hours before dawn.

October 25-26: Moon reaches perigee

The moon will reach perigee – its closest point to Earth in its elliptical orbit, at 3 UTC on October 26, 2023 (10 p.m. CDT on October 25), when it’s 226,720 miles (364,872 km) away.

October 27 and 28 all night: Moon near Jupiter

In the late evening of October 27, 2023, the bright waxing gibbous – an almost full moon – will glow near bright Jupiter. The following evening, on October 28, 2023, the full Hunter’s Moon will rise next to Jupiter shortly after sunset. The pair will travel across the sky together all night.

October 28, all night: Full Hunter’s Moon

The instant of full moon falls at 20:24 UTC (3:24 p.m. CDT) on October 28, 2023.

October 29 and 30 evenings: Moon near the Pleiades

After having visited Jupiter the night before, the bright waning gibbous moon will pass the Pleiades star cluster on the evenings of October 29 and 30, 2023. Pleiades is also known as the Seven Sisters or Messier 45 and appears as a glittering, bluish cluster of stars in the constellation of Taurus the Bull. How many stars can you see in its tiny “dipper-like” shape? The moon and Pleiades will cross the sky together until dawn.

October 31 evening: Moon near Aldebaran

On Halloween, October 31, 2023, the bright waning gibbous moon will lie near the fiery red star Aldebaran of Taurus the Bull. The shimmering Pleiades star cluster will shine nearby. You can follow them until sunrise.

Planets in October 2023

Early-October mornings: Venus and Mercury

Brilliant Venus will climb higher each morning and will reach its greatest elongation from the sun on October 23, 2023. It’ll be 46 degrees from the sun on the dome of our sky that day. Venus will begin the month at -4.4 magnitude. Also, keep an eye on Venus and the bright star Regulus getting closer together at the beginning of the month. They’ll be closest around the morning of October 9, 2023, when they appear about two degrees apart. A lovely waning crescent moon will join Venus and Regulus on the morning of October 10. After that, Venus and Regulus will drift apart. Meanwhile, Mercury will rise in the east shortly before sunrise. Mercury will brighten from magnitude -1.0 to -1.3 before disappearing in the morning sun before mid-month. Its recent September 22 greatest elongation was the best morning apparition for Mercury in 2023 for the Northern Hemisphere.

Mid-October mornings: Venus

After Mercury slips away in the morning sun, Venus will continue to dazzle as a beacon in the morning sky. The bright star Regulus – the bottom star in the backward question mark asterism known as the Sickle – will be nearby. Around mid-month, Venus will fade slightly to -4.3 magnitude. It’ll still outshine all natural objects in the morning sky except the moon. It will rise about four hours before sunrise.

Late-October mornings: Venus

In late October, brilliant Venus will shine at -4.2 magnitude below the bright star Regulus. It will be near the constellation Leo the Lion. After reaching greatest elongation on October 23, 2023, Venus will slowly descend a bit more each day, but it will remain a dazzling light in the morning sky through the end of the year. It will end the month rising about four hours before sunrise.

October evenings, all night: Jupiter

Jupiter will rise in the east shortly after evening twilight subsides and will be visible until dawn. It will shine near the pretty Pleiades star cluster in the constellation of Taurus the Bull. It’s racing toward opposition on the evening of November 1-2, 2023, when we fly between it and the sun. By then, Jupiter will be visible all night. Jupiter lies in the dim constellation of Aries the Ram. It brightens from -2.7 to -2.8 magnitude in October. The moon will float by Jupiter on October 2 and October 29, 2023.

October evenings: Saturn

Golden Saturn will shine in the south after sunset during October. It will be near the dim Water Jar asterism of the constellation of Aquarius the Water Bearer. Our solar system’s beautiful ringed planet is well placed for observation this month and shines at 0.6 magnitude for most of the month. The waxing gibbous moon will visit Saturn on the evenings of October 23 and 24, 2023. Saturn will be setting after midnight this month.

Where’s Mars?

It’s too close to the sun to be visible for the rest of 2023. It’ll be back next year.
