What's Worth Watching in the Sky This October

The youngest planet anyone has ever found was sitting in a filing cabinet. Elias 2-24 b, a Jupiter-size world orbiting a star about 450 light-years away, was confirmed this month at less than a million years old, at least five times younger than the previous record holders. It is still embedded in the dusty disk it formed from, circling 55 times farther from its star than Earth sits from the Sun, and it was pinned down in archived Keck Observatory images from 2018 and 2020, a faint dot that moved. The result, published September 16th in The Astrophysical Journal Letters, is awkward for theory. Giant planets that far out were supposed to need several million years to assemble. As co-author Lucas Cieza put it, even the best planet-formation models are still missing some important processes. The universe keeps filing things before we know what they are.

That is the professional version of skywatching, and it happens in archives. The amateur version happens in your backyard, and October is one of the better months for it. No eclipse falls in October (the year's four are already spent), and no comet is forecast to reach naked-eye brightness, but the month delivers a planet at its annual best, the Moon swallowing another planet whole, and two nights when Earth drives through the exhaust of long-gone comets.

Start with Saturn, which reaches opposition on October 4th. Earth, on its faster inner track, laps Saturn every 378 days or so, and at the moment of passing, the Sun, Earth, and Saturn fall into a straight line with Earth in the middle. That geometry does three things at once. It puts Saturn as close to us as it gets all year, about 784 million miles this time; it shows us the planet's fully sunlit face; and it places Saturn opposite the Sun in our sky, so it rises at sunset, crosses the meridian around midnight, and sets at dawn. Up all night and lit head-on is why an opposition is the brightest a planet ever looks. Saturn will sit at magnitude 0.3 in the dim constellation Cetus, a lone yellowish beacon in the southeast after dark, brighter than anything nearby.

There is a bonus for anyone with a telescope. Last year the rings turned edge-on and nearly vanished; this year they have tilted back open to about seven and a half degrees, enough to see them as a proper band. Around opposition they also do something odd. For a few days on either side of the alignment, the rings surge in brightness and briefly outshine the globe, then settle back. The effect is named for Hugo von Seeliger, who studied it in the 1880s and reasoned from it that the rings must be made of countless small particles. He was right. When the Sun is directly behind us, every icy chunk in the rings hides its own shadow and the whole disk reflects light straight back at the viewer, the way a road sign flares in headlights.

Two mornings later comes the month's best single moment, and it belongs to North America. Before dawn on October 6th, a thin waning crescent Moon, about 19 percent illuminated, passes directly in front of Jupiter, an occultation visible before dawn from parts of the United States, Canada, and Mexico. Jupiter is the brightest thing in the pre-dawn eastern sky this autumn, and its four big moons go behind the lunar limb with it. From Virginia Beach, for example, Jupiter begins to disappear at 4:20 a.m. Eastern and is fully back by 5:26. Times shift by city, so check a local prediction. Jupiter slides behind the bright edge over about a minute, erased rather than switched off, and returns from the unlit edge, materializing out of empty sky. Binoculars will do. Mars is in the same neighborhood, a faint orange point marching toward Jupiter for a close pairing on November 15th, and the gap between them shrinks visibly each week through October.

Then the meteors. Meteor showers happen because comets are messy. Each time one swings through the inner solar system, sunlight boils ice off its nucleus and releases grit that spreads along the comet's orbit like gravel shaken off a truck. Earth's orbit crosses several of those debris lanes, and because our orbit is fixed, we hit each lane on the same calendar dates every year.

The Draconids, on the evening of October 8th, are the leftovers of Comet 21P/Giacobini-Zinner, and they break a meteor-shower rule. Most showers are best after midnight, when your side of Earth faces forward into the debris. The Draconid radiant in Draco is highest as darkness falls, so this shower peaks in the early evening, which suits anyone who refuses to set a 3 a.m. alarm. It is a modest display, perhaps ten meteors an hour under a dark sky, though it has erupted into storms in the past. With the Moon a fading morning crescent, two days before the new Moon of October 10th, the evening sky will be as dark as it gets.

The Orionids are the better show and the better story. They are pieces of Halley's Comet, shed on visits going back centuries, and Earth crosses that trail twice a year; the May crossing produces the Eta Aquariids, and the October crossing produces these. The peak is expected on the night of October 21st into the 22nd, and the nights on either side are worth trying too. Orionids hit the atmosphere at about 41 miles per second, among the fastest of any shower, which is why they often leave glowing trains that linger after the meteor is gone. Expect ten to twenty an hour in a dark sky. A waxing gibbous Moon will wash out the evening, but it sets a few hours before dawn, and the radiant, above Betelgeuse in Orion's raised club, is highest in those same pre-dawn hours.

Venus, which owned the evening sky in September, is leaving it. The planet reached its brightest for the year in the third week of September, when a crescent phase and a growing apparent size combined to maximum effect, a moment this column previewed last month. From here it thins and sinks fast. By early October it sets before the end of evening twilight, and on October 23rd and 24th it passes between Earth and the Sun at inferior conjunction. Within weeks it will reappear before sunrise, climbing toward a second, morning greatest brilliancy on November 29th.

The full Moon arrives on October 26th at 12:12 a.m. Eastern, which for most of the country means the evening of the 25th. It is the Hunter's Moon, the name given to whichever full Moon follows September's Harvest Moon, and it inherits the same trick. The Moon's path makes a shallow angle with the eastern horizon this time of year, so successive moonrises come only about half an hour apart for several nights instead of the usual fifty minutes. The name is a farming calendar's memory of a Moon that showed up early for work when the fields were bare and the game was fat.

September, for its part, went out with a rocket. On September 28th, SpaceX's Starship reached orbit for the first time on its fourteenth flight, released 26 Starlink satellites, and splashed down in the Pacific north of Hawaii about three hours after liftoff. SpaceX brought the ship home at its first scheduled checkpoint rather than flying the planned ten hours, and called the flight a success because it met both primary objectives. The Super Heavy booster splashed down in the Gulf. It was a milestone years in the making, and it arrived on a launch schedule that has a habit of sliding. October needs no launch window. It already has a planet at its closest, a Moon that eats Jupiter, and Halley's dust burning up overhead, and all of it runs on schedule.
