So in that case we must have observed the effect on our orbit from a NEO, wouldn’t that be the case?
Had that happened or not?
More importantly, have we then observed our orbit return to “normal”?
We know they happened. When we returned to the predictable orbit cannot be determined with any accuracy, we just know that it has since the calculations still prove out going in both directions.
Whatever temporary perturbations occurred the numbers still work out.
I hate to have to resort to gross over simplifications but whether you record the exact time the sun rises each day, we know it rose and that it will rise again just as it has throughout the history of the planet.
Yeah, it’s almost like any perturbations never existed in the first place, at least not to any degree that was measurable or observable.
Because as you already pointed out, we’ve only been able to measure these things for an extremely short period of time.
And again whether or not they could be measured at the time in no way indicates they did not occur.
Physics tells us that each of those objects has some effect on the earth.
Okay. But physics doesn’t tell us our orbit is going to return to some magical equilibrium and no observations have demonstrated such an occurrence. All you can say is that we haven’t seen any unpredicted variation in the last 100 years, but that just means there’s been no measureable alteration of our orbit in that time frame one way or another.
That’s nice. Can you show;
- That the orbit then was the same as now.
- A NEO object passed by in the intervening years of such magnitude that it would be detectable beyond the precision of the orbit historical records.
You need to do this to prove out your hypothesis.
It’ll never happen.
You know that.
I know that.
Wildrose will explain how all objects effect our orbit, that there are many NEOs and that there is historical record of orbits being the same as today. “It’s obvious from that point. Clearly you don’t know Physics!”

Yes, that’s what I said, even in a vacuum, eventually the kinetic energy imparted by the pluck is eroded by the friction in the wire. But again, a planetary orbit has no tensile force to negate the force imparted by an NEO if it “plucks” it.
But that is where the comparison breaks down, the disturbed orbit of a planet is NOT like a plucked guitar string. There is no tension pulling it into a straight line, Its new lowest potential energy orbit is wherever the NEO left it.
All we need to do is check those ancient temples and observatories to see if the same alignments still occur to see that we have remained in the same orbit long term.
In the shorter term all we need do is refer to the records of those events and the positions as recorded throughout history.
And you think those temples have the necessary accuracy to detect small differences?
Cmon man. Be reasonable.
There is both gravity and momentum keeping them on and then returning them to the same orbits.
In order for anything to have a permanent effect on our orbit it would have to be sufficient as to over come both the gravity and momentum acting on the planets which are the equivalent of the anchors of the guitar string and tension on it.
Gravity acts in a straight line just like the tendon on the string. Momentum also acts in a straight line. Gravity working in opposition to that straight line converts forward momentum to angular momentum.
You cannot say that absolutely. The affect on the orbit is dependent on the mass of the NEO and how near it passes. There is no possible way to know that it is not appreciable because you have no idea of how many, how large or how close NEOs may have been. Don’t you think that if the NEO that eventually collided with Earth and formed the Moon had never hit us that it would not have caused an “appreciable” change to our obit?
They have the necessary accuracy to show that our orbit has remained relatively stable over the long term since they were built. Some of them are as old as 40,000 years.
We have only been capable of detecting such a perturbation for a couple of hundred years at best. Its not the least bit surprising that we haven’t done so.
The multiple object impact theory is gaining more and more acceptance and the three of them certainly would have had a measurable effect had they passed nearby.
Samm, the moon formed from a collision 4 billion years ago. We are talking about much more recent history. 4 billion years ago the solar system was a chaotic place. Now, not so much.
Yet we’ve had interstellar objects enter our solar system recently as the links provided previously showed.
We also have long period objects passing through as demonstrated in others.
We’ve even had a rogue star pass through our solar system in the past as again, demonstrated previously with the supplied links.
Yes, the orbit has been relatively stable because any near Earth object has had a relatively zero effect.
Remember, we are talking about some of the most minute variations.
