Ancient Meteorite Reveals a Forgotten Planet That Existed 4.5 Billion Years Ago
The analysis of NWA 12774 points to a parent body at least 1,000 kilometers wide and possibly larger than 1,800 kilometers, researchers said.

In 2019, a meteorite recovered in the Sahara desert opened a new track on the early days of the solar system. The object, known as NWA 12774 and with an estimated age of 4560 million years, may have been part of a protoplanet: a primitive celestial body that did not become consolidated as a planet.
Ancient Meteorite Reveals a Forgotten Planet That Existed 4.5 Billion Years Ago
A rare meteorite recovered from the Sahara Desert has revealed compelling evidence for a long-lost world that existed during the solar system’s earliest days. About 4.5 billion years ago, a large planetary body, potentially as large as the Moon or even Mars, orbited the Sun before colliding with another object and breaking apart. Now, researchers [...]
Rare Sahara meteorite may be a fragment of a lost planet destroyed at the solar system's dawn
Scientists have proposed that Northwest Africa 12774, a meteorite recovered from the Sahara Desert, may be debris from a destroyed protoplanet, according to Sci.News. What happened? Dr. Aaron Bell, a researcher at the University of Colorado Boulder, led a team that studied Northwest Africa 12774, or NWA 12774. It's an angrite meteorite that was most likely found in Mauritania. As Sci.News reported, their analysis indicates the rock's source was…
In the distant past, there may have been another planet in the solar system. It was probably about the size of Mars, but it died as a result of a space disaster. And scientists could never have known it if they hadn't discovered its fragments on Earth, says Science Alert. The NWA Meteorite (North-West Africa) 12774 was discovered in 2019 in the Sahara desert. It consists of a dark matrix strewn by small olive crystals, a common group of minerals…
A rare meteorite found in the Sahara Desert may be the last evidence of a protoplanet that existed 4.5 billion years ago. The research, published in the journal Earth and Planetary Science Letters, reveals details about a planetary body that collided and fragmented, contributing to the formation of other planets. Discovery of meteorite in the Sahara Desert The meteorite, named NWA 12774, belongs to a rare class known as angrites. These meteorite…
Rare meteorite points to a long-lost planet from our early solar system
A meteorite found in the Sahara is forcing scientists to rethink what kinds of worlds once circled the young sun. The rock, called Northwest Africa 12774, belongs to a rare class of meteorites known as angrites, some of the oldest volcanic materials ever recovered. For years, their odd chemistry led many researchers to picture their source as a small asteroid. But the new evidence points somewhere much larger. It seems to be a lost protoplanet t…
