The Mental Floss Guide to the November Night Sky

November is a great month for skywatching with two dazzling meteor showers, the rare view of a tiny planet, and an eerie celestial meeting of two bright worlds. None require telescopes or sophisticated knowledge of the sky above. If you have eyes, live on Earth, and want a good dose of the cosmos, you're in for a treat. Here are a few highlights that skywatchers should be on the lookout for.

NOVEMBER 4: FIREBALL SEASON BEGINS

The Taurid meteor shower dominates the early part of November, with the northern and southern hemispheres each getting their own shows. The South Taurids peak after midnight on November 4. The North Taurids peak at the same time, but on different days: the 10th going into the 11th. The source of the Taurids is the debris field of the comet Encke. The meteor stream is massive and spread out, with the gravitational influence of Jupiter, most notably, causing a split and thus the dual peaks.

Meteors, though appearing to be massive chunks of rock coursing toward Earth, are generally dust- or sand-sized particles that burn brightly as they slam into the atmosphere. The Taurids tend to be a bit larger than most, frequently producing what are called "fireballs" (really bright meteors). While you won't see many Taurid meteors per hour (around seven or so at best), what the shower lacks in quantity it makes up for in quality. If you have low levels of light pollution and your eyes are adjusted to darkness, you should be in for quite a show.

NOVEMBER 13: THE JV TEAM DEBUTS

On November 13, Venus and Jupiter will appear alarmingly close in the pre-dawn sky, practically as a single object, separated by a mere 0.3 degrees. But don't worry, the planets aren't colliding. Rather, it's a trick of perspective. Venus is about the size of Earth (it is, in many ways, our evil twin), and is one planet closer to the Sun than Earth in its orbit. It is a stunning, unblinking dot in the sky. Jupiter, meanwhile, is about five times farther from the Sun than is the Earth, but what it lacks in distance, it makes up for in size: you could fit about 1300 Earths inside of it. What makes their conjunction so fun is that you don't have to know much about space or astronomy to see the magic of orbital mechanics. How to see it: One hour before sunrise, look east. The two bright, eerily adjacent worlds will appear on the horizon. As the sun rises over the next hour, it will wash them out, so have coffee with you and enjoy the moment.

NOVEMBER 17: THE BEST METEOR SHOWER OF THE YEAR PEAKS

After midnight on November 17, the Leonids meteor shower will peak, and here is why you need to see it. 1. It coincides with a new moon, which means there will be no moonlight to wash out the sky. 2. This shower has a history of delivering the goods, some years bringing as many as 1000 meteors per minute. Note: This is not one of those years! Expect between 10 and 20 per hour, which still isn't bad when the sky is inky black, a celestial canvas waiting for brushes of light. (Incidentally, while the Taurid meteors collide with Earth's atmosphere at a snail's pace—a mere 65,000 miles per hour—the Leonids do not play around. They're smashing into us at a blistering 160,000 miles per hour.) 3. The 17th is a Friday and you can sleep late the next morning, so what are you going to do: Binge-watch somebody else's adventure on Netflix, or go live your own?

NOVEMBER 24: MERCURY SHINES AT ITS BIGGEST AND BRIGHTEST

Mercury will reach greatest eastern elongation, meaning it will be as far from the Sun as it can get for the rest of the year, relative to the Earth, and will thus be as big and bright as it's going to get in the sky. If you want to see the elusive little planet, this is your big chance. Just before sunset, look west. You will most easily see Saturn not too far above the horizon. As the minutes move forward and the sky slowly darkens, you'll notice another bright spot below Saturn. That's Mercury. Enjoy it while you can, because you'll only have about 30 minutes from its first appearance before it sinks below the horizon and thus falls out of view.

If bad weather ruins any of your November viewings, do not fret. Next month we've got meteor showers, pagan rituals, and supermoons to help bid 2017 adieu.

How to See the Full Sturgeon Moon on Thursday

The full moon of every month has a special nickname. Some—like September's harvest moon, December's cold moon, and May's flower moon—have obvious connections to their seasons, while other names are harder to decode. August's sturgeon moon is an example of the latter. It may not be the prettiest lunar title in The Old Farmer's Almanac, but that doesn't mean the event itself on August 15, 2019 won't be a spectacular sight to behold.

What is a Full Sturgeon Moon?

The first (and normally the only) full moon that occurs in August is called a sturgeon moon. The name may have originated with Native American tribes living around the Great Lakes in the Midwest and Lake Champlain in New England. These bodies of water contain lake sturgeon, a species of freshwater fish that grows up to 6.5 feet in length and can live 55 years or longer. August's full moon was dubbed the sturgeon moon to reflect its harvesting season. This full moon is sometimes called the green corn moon, the grain moon, and the blackberry moon for similar reasons.

When to See the Full Sturgeon Moon

On Thursday, August 15, the full sturgeon moon will be highly visible around sunrise and sunset. The satellite will be 99.9 percent illuminated by the sun when it sets Thursday morning at 5:57 a.m EDT—just nine minutes before dawn. On the West Coast, the setting moon will coincide perfectly with the rising sun at 6:15 a.m. PDT.

If you aren't interested in getting out of bed early to catch the sturgeon moon, wait until Thursday evening to look to the horizon. Twenty-seven minutes after sunset, the full moon will rise on the East Coast at 8:21 p.m. EDT. On the West Coast it rises at 8:10 p.m. PDT, 30 minutes after the sun sets.

The moon generally looks bigger and brighter when it's near the horizon, so twilight and dawn are ideal times to catch the spectacle. But it's worth taking another peek at the sky closer to midnight Thursday night; the Perseid meteor shower is currently active, and though the light of the moon may wash them out, you're most likely to spot a shooting star in the late night and early morning hours.

A Full Harvest Moon Is Coming in September

The Old Farmer's Almanac lists a special name for every month's full moon, from January's wolf moon to December's cold moon. Even if you're just a casual astronomy fan, you've likely heard the name of September's full moon. The harvest moon is the full moon that falls closest to the fall equinox, and it's associated with festivals celebrating the arrival of autumn. Here's what you need to know before catching the event this year.

What is a harvest moon?

You may have heard that the harvest moon is special because it appears larger and darker in the night sky. This may be true depending on what time of night you look at it, but these features are not unique to the harvest moon.

Throughout the year, the moon rises on average 50 minutes later each night than it did the night before. This window shrinks in the days surrounding the fall equinox. In mid-latitudes, the moon will rise over the horizon only 25 minutes to 30 minutes later night after night. This means the moonrise will occur around sunset several evenings in a row.

So what does this mean for the harvest moon? If you're already watching the sunset and you catch the moonrise at the same time, it will appear bigger than usual thanks to something called the moon illusion. It may also take on an orange-y hue because you're gazing at it through the thick filter of the Earth's atmosphere, which absorbs blue light and projects red light. So if you've only seen the full harvest moon around sunset, you may think it always looks especially big and orange, while in reality, any full moon will look that way when it's just above the horizon.

When to See the Harvest Moon

This year, the harvest moon will be visible the night of Saturday, September 14—about a week before the fall equinox on September 23. The moon will reach its fullest state at 12:33 a.m. ET—but if you're still convinced it's not a true harvest moon without that pumpkin-orange color, you can look for it at moonrise at 7:33 p.m. on September 13.
