ExtremeTech Meteorite Fragment Points to Missing Dwarf Planet in Early Solar System By Ryan Whitwam on December 22, 2020 at 1:36 pm This site may earn affiliate commissions from the links on this page. Terms of use. Every asteroid that falls to Earth is a potential window into the origins of the solar system, but scientists have stumbled upon something quite strange when studying a fragment of the Almahata Sitta asteroid. It contains evidence of a huge, previously unknown object in our solar system — perhaps a long since destroyed dwarf planet.  The Almahata Sitta asteroi...

Meteorite which hit Earth ‘came from unknown object up to 1,100 miles wide’ Rob Waugh The meteorite came from a large object, and formed in the presence of water (SWRI) A meteorite which hit Earth in 2008 came from a much larger, unknown object roughly the size of Ceres, a 500-mile-wide object in the main asteroid belt.  The  Almahata Sitta (AhS) meteorite was formed in the presence of water, researchers from the Southwest Research Institute now believe.  It was the first time scientists had predicted an asteroid impact prior to its arrival, and allowed the recovery of...

Meteorite Remains Traced to Enigmatic 'Ceres-Sized Unknown Object', Media Says Subscribe Sputnik International https://sputniknews.com/science/202012221081539591-meteorite-remains-traced-to-enigmatic-ceres-sized-unknown-object-media-says/ While the parent body of the meteorite studied by the research team is reportedly believed to no longer exist, its very presence in our solar system suggests that other similar objects “could potentially have done the same”. Having studied the remains of a meteorite that exploded above Sudan back in 2008, a team of scientists managed to obtain important...

Meteoric Evidence For A Previously Unknown Asteroid Press Release - Source: SWRI meteorite Almahata Sitta section A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago. The composition of a piece of the meteorite Almahata Sitta (AhS) indicates that its parent body was an asteroid roughly the size of Ceres, the largest object in the main asteroid belt, and formed in the presence of water under intermediate temperatures and pressures. "Carbona...
