Early planetary migration in the solar system has been long established, and there are myriad theories that have been put forward to explain where the planets were coming from. Theories such as the Grand Tack Hypothesis an the Nice Model show how important that migration is to the current state of our solar system. Now, a team from Lawrence Livermore National Laboratory (LLNL) has come up with a novel way of trying to understand planetary migration patterns: by looking at meteorite compositions.
The researchers, led by postdoc Jan Render, had three key realizations. First, that almost all the meteorites that have fallen to Earth originated from the asteroid belt. Second, that the asteroid belt is known to have formed by sweeping material up from all over the solar system. And third, and perhaps most importantly, that they could analyze the isotopic signatures in meteorites to help determine where a given asteroid had formed in the solar system.
With that knowledge, they could then extrapolate out to other asteroids of the same type. There are approximately 100 different types of asteroids, with different isotopic signatures, in the asteroid belt.

I would ask Pelosi. I’m sure that she was present.

What Did The Solar System Look Like Before All The Planets Migrated? The Sun should have built a wall...

This is the first time I heard of the planet migration issue. Certainly, a tax is needed to stop this dreadful event.

False premise, first sentence.
From when and by whom? Impossible to verify experimentally. Pure conjecture. Must humanity know evrything— even that which cannot be known? Deut. 29:29.

I’m always skeptical about how they know what the origins of planets and asteroids. They rely on an accretion model which postulates that all of the planets and lesser bodies were originally gas and dust that clumped together.
Oh, and Klingons around Uranus.

Yep. A lot of guessing and bold assumptions in that first sentence.

I believe there is a photograph of what it looked like back then.

Was this illegal migration or legal migration?
To: BenLurkin
I’ll field that question. Before the planets migrated, the Sun was happy and carefree. It didn’t have to worry about the effects of solar flares, global warming, or anything like that. Yes, the Sun was happy and carefree.
Here’s an artist’s rendition of the Sun at that time.

Dunno, but libtard profs would say with 100% certainty, it was racist, sexist and homophobic.

Well, the immediate neighborhood rejoiced when Uranus moved to the nether regions.
