In 2029, it’s possible that a major event will occur inside the heavens above the Earth, which is causing skywatchers and scientists to be concerned. On the 13th of April of that year, an asteroid referred to as Apophis will skip through, coming closer to us than any previous rock of its duration has ever been.
According to their point, Apophis can be 340 meters in size, equivalent to 1100 ft, and it will come within 31,860 kilometers, equal to 19,794 miles, of the surface of our planet. It can also appear like a huge hole, but in fact, it’s far more constrained than the space through which a number of our satellites are able to escape.
At this factor, you are probably wondering, “Uh oh, what can show up if this boulder within the location decides to show up at the birthday party?” But you should not worry about it just but. After accomplishing the necessary calculations, the experts have come to the realization that it’s miles highly unlikely that Apophis will make any unscheduled landings on Earth in the year 2029.
Researchers, however, consider this near-shave to be similar to a golden price tag. They are all prepared to examine Apophis as it whizzes through, gathering records to assist them in determining the path wherein this rock will go in their destiny.
So fasten your seatbelts, anyone. The time has come to gather extra understanding regarding this first-rate piece of space junk.
Asteroid Apophis Flyby
In 2029, keep your eyes peeled for a cosmic visitor named Apophis. This space rock is planning to swing by Earth at a distance of just 19,794 miles from our turf.
Now, what’s really intriguing about Apophis isn’t just its trajectory but its name, too.
You see, the moniker “Apophis” has its roots in ancient Egyptian tales. Back in the day, the Egyptians spun stories about a troublemaking serpent or dragon god named Apophis, also known as Apep. This dude symbolized chaos and destruction, a real cosmic troublemaker.
So why name an asteroid after this mythic troublemaker? Well, it’s because Apophis, the asteroid, poses a potential threat to Earth. Its close encounters with our planet hint at chaos and mayhem, just like its mythological namesake.
In a way, Apophis isn’t just a wandering space rock; it’s a reminder of how fragile our cosmic order can be and how a tiny disturbance from the vastness of space could shake things up down here on Earth.

Theoretical Strength of the Impact
Even though scientists are pretty confident that Apophis won’t crash into Earth, it’s still kind of fun to imagine what would happen if it did.
So, let’s get our math hats on and do some theoretical calculations.
Picture this: Apophis, with its estimated width of 340 meters, decides to give Earth a big ol’ hug at speed similar to other asteroids its size, which can range from 20 to 70 kilometres per second.
To understand the potential impact, we’ll use a basic formula for kinetic energy: 1/2 x mass x velocity2. But first, we need to figure out the mass, which means estimating Apophis’s density. Scientists usually reckon it’s similar to the density of rock, about 2.5 grams per cubic centimetre.
Let’s play it safe and say Apophis is cruising along at a modest 20 kilometres per second (that’s on the slower side for asteroids).
We’ll convert that diameter into meters (340 meters), then calculate the mass using the formula for the volume of a sphere (4/3 x π x radius^3), assuming Apophis is a lovely, round sphere.
Once we’ve got the mass sorted, we’ll plug it into the kinetic energy formula to give us a rough idea of the energy that’d be unleashed if Apophis and Earth decided to get up close and personal. Remember, this is just a ballpark figure. The actual impact could be a whole different story, depending on a bunch of factors.
So, let’s see the final calculation:
Volume = 4/3 × π x (radius)3 = 4/3 × π x (170)3 ≈ 6.16 × 107 cubic meters
Now, let’s find the mass of Apophis:
Mass = Volume * Density ≈ 6.16 × 107 cubic meters * 2.5 grams/cubic centimeter ≈ 1.54 × 1011 kilograms
Finally, we’ll calculate the kinetic energy using the velocity:
Kinetic Energy = 1/2 × Mass × (Velocity)2 ≈ 1/2 × 1.54 × 1011 kg × (20,000 m/s)2 ≈ 3.08 × 1019 joules
The predicted kinetic energy released upon impact would be substantial, maybe equivalent to tens of thousands of megatons of TNT, given the 340-meter diameter.
Lastly, let’s compare the estimated kinetic energy of the impact of Apophis with the power generated by the atomic bomb unleashed on Hiroshima.
- Estimated Kinetic Energy of Apophis Impact: 3.08 × 1019 joules
- Energy Released by Atomic Bomb on Hiroshima (Little Boy): Approximately 63 terajoules (6.3 × 10^13 joules)
Now, let’s put these figures into perspective:
The estimated kinetic energy unleashed by Apophis, boasting a 340-meter diameter, dwarfs the energy of the atomic bomb dropped on Hiroshima. We’re talking about a whopping 488,000 times more power packed into that impact.
This stark comparison really drives home just how much destruction a cosmic collision can bring. It’s a stark reminder of why it’s so crucial to keep a close eye on space rocks like Apophis and figure out ways to steer them away from Earth.
Sure, the aftermath of the Hiroshima bomb was devastating. Still, the fallout from a collision with a behemoth like Apophis could be catastrophic on a whole other level.
So, as we wrap up, it’s worth pondering: What more can we do to safeguard our little blue planet from these cosmic threats?
When Will Aphophis Hit Earth, if Ever?
So, we’ve established that Apophis won’t be paying us any surprise visits in 2029 or even in 2036. But what about further down the line? Say, in 2050 or 2100?
Well, according to the latest number crunching, Apophis isn’t planning on crashing our party in the next century, either.
Now, while it’s impossible to say for sure what Apophis will get up to in the future, history gives us a guide. Asteroids similar in size to Apophis, roughly around 370 meters wide, tend to make friends with Earth’s surface about once every 80,000 years or so, on average.
So, for now, we’re in the clear. Who knows what the future holds? One thing’s for sure, though: by the time any potential threat comes knocking (thousands of years from now), we’ll have some pretty nifty tech up our sleeves to deal with it from a safe distance.
