A meteorite discovered in Northwest Africa... Scientists say this ancient rock -- formed more than 4.56 billion years ago -- proves that planet-building processes in the outer reaches of the solar system began just as quickly as they did closer to the Sun.
In a study published in Communications Earth & Environment, researchers analyzed a rare meteorite known as Northwest Africa (NWA) 12264, revealing that the body it originated from -- a fully formed protoplanet beyond Jupiter -- was already active during the very dawn of the Solar System.
The findings challenge the prevailing assumption that outer Solar System planets formed more slowly due to cooler temperatures and higher ice content and instead suggest that planetesimal formation was a synchronized, system-wide phenomenon...
The dunite meteorite -- a rock type typically found in planetary mantles -- contains key isotopic clues indicating it formed on a large, layered protoplanet with a metal core and silicate mantle, much like Earth. Crucially, the radiometric dating of its minerals places its formation just a few million years after the birth of the Solar System itself.
Using high-precision lead-lead (Pb-Pb) and aluminum-magnesium (Al-Mg) dating techniques, scientists determined the age of NWA 12264 to be around 4,569.8 ± 4.6 million years, making it older than any previously studied rock from the outer Solar System.
The aluminum-magnesium method yielded a slightly younger age of 4,564.44 ± 0.30 million years, but both values are significantly earlier than those from other known outer system meteorites... clearly indicate that its parent body -- an ancient, now-shattered protoplanet -- must have accumulated, differentiated, and broken apart in rapid succession, likely within the first few million years of the Solar System's formation.

Adds some data to Tom Van Flandren’s exploded planted theory.

Oh man! That thing is way past its maintenance checkpoints.
Scientists are never wrong. Until they say they are wrong. Then it’s OK because they then become right and all their theories should be honored again.

Yes its been waiting for a very long time, but hopefully we’ll et there in time to fix it right as rain.
Scientists don't claim to never be wrong, that's the exclusive domain of politicians.
Science is a method, not a body of knowledge, and it's the best way to study physical phenomena.
Yeah, exactly. Alas, I believe TVF’s website’s gone now, but probably survives in the Internet Archive. Someone was keeping it alive for at least few years after he passed. I can’t remember the domain name at this point.
Hmm, here’s a reference to his book about the EPH:

Oh, okay, his website’s back and lookin’ all spruced up:
“was already active during the very dawn of the Solar System.”
Is this a pun or a metaphor
