Short answer first, because it’s the question everyone actually wants settled: no. Asteroid 2029 Apophis will not hit Earth. On April 13, 2029, this stony near-Earth asteroid, about 340 meters across, will sweep past our planet at roughly 32,000 kilometers, closer than many of the satellites we rely on every day, and then carry on around the Sun without leaving a scratch.
But the fact that it misses is exactly what makes it worth talking about. For a few tense years after its discovery, Apophis was the scariest rock in the sky. Now it is about to become one of the greatest free shows astronomy has ever offered, and a rare chance to watch a planet reach out and nudge an asteroid in real time.
Named After a God of Chaos, and for Good Reason
Apophis was discovered on June 19, 2004, by three astronomers, Roy Tucker, David Tholen, and Fabrizio Bernardi, working at Kitt Peak in Arizona. It did not stay quiet for long.
Within months, the early orbit calculations threw up a genuinely alarming number. There appeared to be about a 2.7 percent chance, roughly 1 in 37, that Apophis would slam into Earth in 2029. That may not sound huge, but for an object this size it was terrifying, and it pushed Apophis to level 4 on the Torino impact scale, the highest rating any asteroid has ever received. The discoverers gave it a fitting name. Apophis, or Apep, was the ancient Egyptian serpent-god of chaos and darkness, the sworn enemy of the Sun. A rock that looked like it might end cities got a villain’s name to match.
Then the story turned. As telescopes tracked Apophis month after month, and especially after detailed radar observations in 2021, its future path was pinned down with real precision. The impact scenarios for 2029, 2036, and beyond fell away one by one. Today both NASA and ESA are clear about it: there is no risk of Apophis striking Earth for at least the next hundred years. The god of chaos, it turns out, is just passing through.
Just How Close Is Close?
Here is where the numbers get genuinely startling.
At its nearest, Apophis will pass about 32,000 kilometers, roughly 20,000 miles, above Earth’s surface. To put that in perspective, the satellites that beam your TV and weather data sit in geostationary orbit at around 36,000 kilometers. Apophis will slip in closer than that. It will be less than a tenth of the distance between Earth and the Moon.
For a chunk of rock about 340 meters wide, taller than the Eiffel Tower, this is unheard of. Small asteroids buzz Earth all the time, but they tend to be the size of cars or buses. Something this big coming this close, with the date known years ahead, has never happened in recorded history. If you want to understand where objects like Apophis come from and how they end up on Earth-crossing paths, our guide to the asteroid belt is a good place to start.
To be clear, that satellite comparison is about altitude, not a collision course through a crowded lane. Apophis will not be weaving between spacecraft. It simply dips below the height where those satellites orbit, which is remarkable enough on its own.
You Might Be Able to See It With Your Own Eyes
This is the part that turns a scientific event into a personal one.
On the night of April 13, 2029, Apophis will not need a telescope. From parts of Europe, Africa, and western Asia, it should be visible to the naked eye as a modest point of light around magnitude 3, about as bright as the fainter stars in a familiar constellation. It will drift across the sky in the region of Cancer, and if you watch closely you’ll catch it moving, covering roughly the width of a full Moon every minute. That is fast for something in the night sky.
Recent visibility studies suggest that when you add up everywhere the asteroid climbs above the horizon during its several-hour passage, a large fraction of the world’s population, possibly most of it, will be somewhere it could be spotted. Weather and light pollution will decide who actually gets the view, but the raw geometry is on our side. If you’ve never tried tracking a moving object against the stars, our roundup of great comets and other naked-eye sky wonders is a nice warm-up for the kind of patient sky-watching this will reward.
Earth Is About to Run a Physics Experiment on an Asteroid
The flyby is not just a spectacle. It’s a laboratory.
When Apophis passes this close, Earth’s gravity will tug on it hard enough to leave marks. Scientists expect the encounter to bend the asteroid’s orbit, tweak the way it tumbles, and possibly shift loose rocks and dust around its surface, a kind of gentle planetary massage. Watching how a small body responds to that tugging tells researchers things about its insides that no telescope on the ground could ever reveal. Is Apophis a solid lump or a loose pile of rubble held together by weak gravity? The 2029 flyby should help answer that, and answers like these feed directly into planetary defense, the science of protecting Earth from the asteroids that genuinely could pose a threat one day.
Two spacecraft are getting involved. NASA is sending OSIRIS-APEX, which is the same probe that visited asteroid Bennu and dropped a sample back to Earth in 2023 under its old name, OSIRIS-REx. Rather than retire it, NASA redirected it to meet Apophis, arriving just after the flyby to study the asteroid for around 18 months. It may even fire its thrusters at the surface to blow away the top layer and peek at what lies beneath. Meanwhile the European Space Agency, working with Japan, is preparing a mission called RAMSES to reach Apophis before the encounter, so it can watch the asteroid change as it happens. You can read NASA’s own overview of the plans on its Apophis mission page, and ESA lays out its side of the story on the agency’s Apophis planetary defense page.
Why This One Matters More Than the Scary Headlines
It’s easy to be numb to asteroid news. Every few weeks a headline warns of a “city-killer” skimming past, and nothing happens, because almost all of them were never going to hit anything. Apophis is different for a simple reason. It is big, it is close, the date is locked in, and the danger has already been taken off the table.
That combination is what makes it special. We get all the drama of a giant rock threading the needle past our planet, with none of the actual threat. For one evening in April 2029, millions of people will be able to step outside, look up, and personally watch an object that once carried the highest danger rating ever assigned to an asteroid glide harmlessly overhead. Events like this are also a reminder of why sky-watching is worth building into your life, and if you’d like more reasons to keep looking up between now and then, our complete guide to the Perseid meteor shower is a great next stop.
Mark the date. April 13, 2029. A Friday the 13th, of all days, when the god of chaos shows up right on schedule and, for once, behaves himself.
