Arrokoth is a trans-Neptunian object located in the Kuiper Belt, the last extensive layer of debris in the solar system. It is made up of two larger rock fragments that are "welded" together and, together, is only kilometers in size. The New Horizons probe managed to photograph it in January , making it the most distant and primitive object explored by a spacecraft from Earth. Since then, Arrokoth has helped solve one of the main unknowns about the origin of the planets.
This stellar object has at least mounds in one of its lobes. These clumps of matter are patches that have become attached to a central object as it floats through the solar system . The scientific community has determined that Arrokoth is on its way to beco Chinese Overseas Asia Number Data ming a planetesimal , that is, an "embryo" of a planet. If it encounters enough debris, it will gradually attach itself to the body until it has the mass necessary to generate a significant force of gravity.
Arrokoth's morphology shows no signs of fractures or collisions. The material that composes it did not come to it due to an intense collision at high speeds, but rather came together gently at a speed of just a few meters per second. For decades, astronomers believed that planets formed exclusively through violent collisions. The theory about the origin of worlds changed dramatically thanks to this trans-Neptunian object remaining unchanged for billions of years. The New Horizons team responsible for photographing it described it as a "fundamental brick fossil from which the solar system was built."

The latest study on Arrokoth.
A recent study published in the Journal of Planetary Science found that each of the Arrokoth mounds exhibit structural similarities to each other. The scientists in charge of analyzing the data suggest that these blocks have a common origin. Although it is not certain whether the matter comes from the Kuiper belt , at least it is known that they are from the same class of objects. This new information will be essential for future computational models that attempt to accurately recreate the planet formation process. The team behind the report believes that Arrokoth's patches could be repeated on other bodies in the stage before they become planetesimals.

"It will be important to look for mound-like structures in the planetesimals observed by these missions to see how common this phenomenon is, as an additional guide to theories of their formation," said Alan Stern, associate vice president of the South Research Institute, where it was conducted. the most recent analysis of Arrokoth.
The binary body is named after the word 'arrokoth' which means 'heaven' in the dialect of the Native American peoples. It also has the nickname 'Ultima Thule', the Roman expression used to refer to any distant object beyond the borders of the known world.
