Diamonds in Sudan Meteorite 'Are Remnants of Lost Planet' (theguardian.com) 43

Diamonds found in a meteorite that exploded over the Nubian desert in Sudan a decade ago were formed deep inside a "lost planet" that once circled the sun in the early solar system, scientists say. From a report: Microscopic analyses of the meteorite's tiny diamonds revealed they contain compounds that are produced under intense pressure, suggesting the diamonds formed far beneath the surface of a planet. In this case, the mysterious world was calculated to be somewhere between Mercury and Mars in size. Astronomers have long hypothesised that dozens of fledgling planets, ranging in size from the moon to Mars, formed in the first 10m years of the solar system and were broken apart and repackaged in violent collisions that ultimately created the terrestrial planets that orbit the sun today.

    • No, not "Planet X;" rather, the missing fifth planet - where the asteroid belt now lies... possibly related to whatever event(s) caused Mars to get dusted with Xenon 129 a few hundred million years back? ;)

        My understanding is that due to Jupiter's gravity, there never was a planet there. Also the reason that Mars is on the small side.

          My understanding is that astrophysicists hugely dislike catastrophic system models. So hypothesis based around recent major impacts are shunned. So anything like a planet being struck and knocked out of orbit and losing its moon and in passage affecting the orbits of other planetary bodies would be pathologically avoided because it if could happen reality recently in the past millions of years it could happen again and they really hate mentioning that. Even when quoting odds on free flying planets or stars,

    Couldn't the meteorite just be part of the Earth that was knocked loose when a huge rock smashed into and created the moon?

      Mars meteorites are determined because their oxygen isotope ratios match that found on Mars and don't match that normally found on Earth. If the isotope ratios in these meteorites (perhaps of carbon since we talking about diamonds) are atypical of Earth then it stands to reason they came from somewhere else. It could still have come from the collision that created the Moon though. The object that hit the Earth is thought to have been about the size of Mars.

    I hope they can find this lost planet and return it to its rightful owners.

    Anyone who has lost a planet within the past 4 billion years should please contact lost and found, and provide a description of the missing planet.

    Hard to call it a planet, since there is a fair chance that it might still be in one piece if it had cleared its orbit...
  • So I was watching one of those Babylonian Ancient Aliens videos on Youtube, to kill time, and they started talking about this extra planet in our solar system that apparently held a more advanced race and were seen as Gods according to some ancient Babylonian manuscripts / legends. Three weeks after laughing that one off I come to read this. Expect the Ancient Aliens community to go nuts :/

    • our early solar system had a large amount of those, not just one. a lot of them are still around, further away after Jupiter flung them out. others shredded. still that would be long before multicellular life on earth came around

        And some are still around. Some planetary scientists say that the large rocky moons of Jupiter and Saturn were originally inner orbit planets that were captured during the Grand Tack.

  • I find the brilliance of our scientific community astounding, their ability to form the opinion that the planet these rocks originated from was in our solar system is an astounding break through in science, considering how large space is and how many other places these may have come from, to narrow it down to our solar system is truly amazing.
  • Studies show that the meteorite was aiming for Nigeria instead of Sudan, in an interplanetary effort to release a certain prince and allow him to recover his billion dollar financial empire.
