According to the associated press,One year after NASA's new horizons probe flew over a snowman like edge object of the solar system nicknamed "the end of the earth", it is still 4 billion miles away from the earth, revealing the secret of "the end of the earth" for mankind.
According to reports, the latest data shows that scientists found that the surface of this object, known as "the ends of the earth", is relatively smooth, and there are far fewer craters than expected. It looks red, which scientists believe is caused by changes in the organic matter on its surface, which is common in the Kuiper belt.
In addition, despite the presence of frozen methane on celestial bodies, no water has been found.

Alan Stern, chief scientist at the Southwest Institute, also said the "ends of the earth" were roughly the size of a city at a press conference in Seattle on Monday.
According to the previous report, "ends of the earth" is composed of two distinct small objects, the huge flat body ("ends of the earth") and the round small object ("ends of the sea") are connected by "neck".
It is reported that the "new horizon" probe flew over the "ends of the earth" on January 1, 2019, and successively returned data. It is located in the Kuiper belt. The Kuiper belt is a disk of frozen material that orbits the sun more than 2 billion kilometers from Neptune, the eighth largest planet, and 1.5 billion kilometers from Pluto, the dwarf planet visited by New Horizons in 2015.
It is estimated that there are tens of thousands of members of the Kuiper belt, such as the "ends of the earth", which have been in severe cold for a long time, thus providing clues to how the solar system formed 4.6 billion years ago.
