2010 RJ53
The asteroid that’s making a flyby this week on September 9 is the 774-metre large 2010 RJ53.
It is expected to fly by around 366,000 kilometres away from the planet, indicating that it will actually be closer to Earth than the Moon that’s around 384,400 kilometres away.
2021 PT
Sunday i.e. on September 11, we’ll see another asteroid dubbed 2021PT. Although not as large as the 2010 RJ53, it's still quite substantial at around 137 metres in diameter at a distance of around 4.9 million kilometres away from Earth.
2021 NY1
The third asteroid that’s expected to fly by Earth on September 22nd, is the 2021 NY1 asteroid that has also been flagged as a Potentially Hazardous Asteroid (PHA) by NASA Jet Propulsion Laboratory (JPL). It has also been categorised as a NEO (near-Earth object)...
This is also an Apollo-class asteroid and is expected to be around 130 to 300 metres in diameter.
According to NASA, this flyby is going to be its closest approach in almost a century.

I guess space constitutes a different version of “really close”, than I do.
“I guess space constitutes a different version of “really close”, than I do.”
I think the point is that it takes just ONE, small, navigation error and one of those damn things will crash into Earth.
Well, if it hits us, I won’t have to go to work again...
200k miles is nothing. Scary close. And this is one is suspected of being up to a 1000 feet in diameter?
Imagine a 1000 foot iron rock impacting a land mass coming in at about 25 milers per second
If it landed in the ocean it would probably generate a tidal wave.
People scoff at these things but eventually one of them will hit us. Hopefully by the time that happens we will be able to deflect them and swat them away like flies.
Hitting ocean (or polar icecap) would be worse...
Better late than never...
What? Five times the distance to the moon?
Kilometers mean nothing to me.
I know, I could translate it to American if I was really curious how close these asteroids will come.
But I think I’ll just wait for the American version of this story.
The moon will protect us. That's why it's there!
(okay, so I've been watching the Outer Limits...)
You win the thread.
According to some computer models, an 850 foot diameter object/asteroid, traveling at about 25 milers per second would create tsunami waves of about 800 feet high.
It all depends of the object size, mass, angle, speed etc...
Redirect the trajectory of at least one of them towards Afghanistan!
The hazard is humans, as always. Humans who might place rocket engines at just the right spot on a grazer asteroid to give it a last-minute nudge towards a selected spot on Earth.
It will happen, just a matter of when.
But only 18,000 kilometers distant from the orbit of the moon? That could be interesting. I hope the timing is right.
774 meters = .48 mile
That’s kind of what I imagine the great flood was caused by
