A recent NASA study further outlined the geological information of Arrokoth, a “space snowman”, showing that it has a smoother surface and complex geological features and has not yet found water. The study was published in Science. The Space Xher is the farthest object ever visited by humans, located on the edge of the solar system, in the Kuiper Belt, codenamed “2014 MU6.”
In January 2019, NASA’s New Horizons probe flew over the small object, capturing close-ups of the small object. The small object is a kind of “twin star”, that is, by the two celestial bodies slowly, gently combined, in the appearance of two asymmetrical leaf-like structure, shaped like a snowman, “space snowman” nickname d’ name. The small object has a total length of 31 km, the widest point is only 19 km, the surface is light red.
The study found that the surface of the “space snowman” was relatively smooth, with far fewer craters than expected. The slight crater suggests that its formation dates back 4.5 billion years to the formation of the solar system, and that the formation of the sun at the same time is likely to give us information about the formation of the sun. Neither the “body” nor the “head” of the Snowman is completely round, but it is not like the flat pancake shape proposed by scientists a year ago. Despite the presence of frozen methane on the small object, no trace of water has been found.
