A year after NASA’s New Horizons probe flew over a snow-like edge object nicknamed the “End of the Earth”, it is still 4 billion miles from Earth, revealing the secrets of the “end of the earth” for mankind, the Associated Press reported.
Scientists have found the surface of the object, known as the “end of the earth,” relatively smooth, with far fewer craters than expected, according to new data. It’s very red-faced, and scientists believe that this red hue is caused by changes in organic matter on its surface, which is common in the Kuiper Belt.
In addition, despite the presence of frozen methane on the celestial body, the presence of water has not yet been found.

Alan Stern, chief scientist at the Southwest Research Institute, said at a press conference in Seattle on Wednesday that the “end of the world” is roughly the size of a city.
According to previous reports, the “end of the earth” consists of two very different small objects, the huge flat body (“Tianya”) and the round small celestial body (“the sea corner”) connected by the “neck”.
It is reported that the New Horizons probe flew over the “end of the world” on January 1, 2019, and sent back data one after another. It is located in the Kuiper Belt. The Kuiper Belt is a disk of frozen matter that orbits the sun more than 2 billion kilometers farther than Neptune, the eighth-largest planet, and 1.5 billion kilometers further than Pluto, the dwarf planet visited by New Horizons in 2015.
It is estimated that there are thousands of members of the Kuiper Belt, such as the End of the Earth, who have been in freezing conditionfor for so long, providing clues as to how the solar system formed 4.6 billion years ago.
