If you were around in 1986, you probably remember the hype. Everyone was talking about Halley's Comet. People bought telescopes, stayed up late, and... mostly saw a blurry smudge. It was kind of a letdown for the average person. But honestly, the Halley's comet next passing is looking like it’s going to be a completely different story.
We’re currently in 2026. The comet is trillions of miles away right now. It actually hit its farthest point from the sun—called aphelion—back in December 2023. Now, it’s officially on the "downhill" trek back toward us. It’s picking up speed, falling back into the inner solar system for its big 2061 debut.
The 2061 Return: What Most People Get Wrong
A lot of folks think comets are just random. They aren't. Halley's is like clockwork, mostly. It shows up every 75 to 79 years. The reason the last trip in '86 sucked for viewers in the Northern Hemisphere was simple geometry. The comet was on the opposite side of the sun when it was at its brightest. We were looking through the sun's glare at a fading rock.
In 2061, things flip. The comet will be on the same side of the sun as Earth. This is huge. It means the comet will be roughly 12 times brighter than it was in the eighties. We’re talking about a magnitude of -0.3. For context, that’s brighter than almost every star in the sky except for Sirius. You won't need a fancy $2,000 telescope to see it; you’ll just need to look up.

Key Dates for Your Calendar (Seriously, Save These)
The timeline is pretty set. According to NASA’s JPL data, the big moments happen in mid-summer.
- July 28, 2061: This is perihelion. The comet is closest to the sun.
- July 29, 2061: The day after, it makes its closest approach to Earth.
- August 2061: This is the "Golden Month" for viewing.
For those of us in the Northern Hemisphere, it’s going to start low in the morning sky in June. By July, it shifts to the evening. You’ll see it in the northwest after sunset. It’ll be hanging out in the constellation Lynx and then move into Leo.
Why Halley’s Comet Next Passing Actually Matters
It’s not just a pretty light. This thing is a time capsule. It’s about 9 miles long—roughly the size of Manhattan—and it’s made of "primitive" material from the birth of our solar system. When it gets close to the sun, the ice turns to gas (sublimation), and it blasts out these massive jets of dust.

Back in 1986, the European Space Agency sent the Giotto spacecraft to fly right past the nucleus. They found out it’s blacker than coal. It only reflects about 4% of the light that hits it. Basically, it’s a giant, dirty, organic-rich snowball.
Science is already planning for 2061
You might think 35 years is a long way off. It’s not for space agencies. There are already papers circulating at NASA and ESA about "rendezvous missions." A flyby is fast and dangerous because Halley travels in a "retrograde" orbit. That means it goes the opposite direction of the planets. It’s like a head-on collision at 157,000 mph.
To actually "park" a spacecraft next to Halley in 2061, we’d need to launch by 2040 or 2049 to use a "Jupiter Gravity Assist." It takes a decade of swinging around planets just to catch up to this thing.

The History Nobody Talks About
We’ve been watching this comet since at least 240 BCE. The Chinese recorded it in the Shiji. It’s on the Bayeux Tapestry from 1066. King Harold II saw it right before he lost the Battle of Hastings—he thought it was a bad omen. He was right, I guess.
Then you have Edmond Halley. He didn’t discover it; he just realized the comets of 1531, 1607, and 1682 were the same guy. He used Newton’s new laws of gravity to predict it would come back in 1758. He died before he could see it, but when it showed up right on time, it changed science forever. It proved that gravity works on everything, not just planets.
Misconceptions to Clear Up
- It’s not "on fire": Comets don't burn. They're outgassing. That tail is just dust and ionized gas pushed by the solar wind.
- It’s not dangerous: Even though NASA labels it a "Near Earth Object," the 2134 passing is the one that gets "close." In 2061, it stays a safe 0.47 AU away (about 43 million miles).
- The tail doesn't follow it: The tail always points away from the sun. So when the comet is leaving the solar system, it’s actually traveling tail-first. Kinda weird, right?
How to Prepare for the 2061 Show
If you're planning to be around for the Halley's comet next passing, you need a strategy. This isn't a "one-night-only" event; it'll be visible for weeks.
- Find a "Dark Sky" spot: Light pollution is way worse now than in 1986. Check a Bortle scale map. You want a site that’s at least a Level 3 or 4.
- Get stabilized binoculars: You don't need a telescope, but 10x50 binoculars make the tail look incredible.
- Learn the "Averted Vision" trick: Don't look directly at the comet. Look slightly to the side of it. Your peripheral vision is more sensitive to light, so the "fuzz" of the coma will actually look brighter.
- Follow the Orionids: Every October, Earth passes through the debris trail Halley left behind thousands of years ago. These are the Orionid meteor showers. It’s basically the only way to "touch" the comet right now.
The 2061 return is going to be the astronomical event of the century. We're talking about a bright, naked-eye object with a tail stretching across a huge chunk of the sky. If you missed the "blur" of '86, hang tight. The universe is giving us a much better show next time.
Next Steps for You
- Check the Orionids: Mark your calendar for October 21-22 this year. Watching these meteors is the best way to see the "leftovers" of Halley's Comet while we wait for 2061.
- Look at the 1986 Archives: Search for the "Giotto Mission" images from ESA. Seeing what the actual "potato-shaped" nucleus looks like will give you a better appreciation for the "smudge" you'll see in the sky later.
- Track the Position: Use a tool like TheSkyLive to see exactly where 1P/Halley is in the constellation Hydra right now. Even if you can't see it, knowing it's finally headed our way is pretty cool.
