According to a report in New Scientist, the youthful looking family of objects were found in the Kuiper Belt, a ring of icy objects beyond Neptune. They appear puzzlingly fresh-faced, despite the fact that they probably formed in a collision more than a billion years ago. The largest member of the family, a rapidly tumbling blimp-shaped object called 2003 EL61, was discovered in 2005. In 2007, astronomers found five smaller objects travelling in similar orbits. Their paths suggested they all formed a single object that was broken apart in a collision more than a billion years ago. Now, a team led by David Rabinowitz of Yale University in New Haven, Connecticut, US, reported that the brightness of the large object and four of the smaller ones changes little when observed from various points along Earths orbit. That suggests their surfaces are covered with fresh powdery ice no more than 100 million years old. A fresh surface is understandable for the biggest object, 2003 EL61, because it is large enough to hold an atmosphere that vaporises and refreezes regularly. But the four smaller family members are too small to hold atmospheres, said Rabinowitz... Something fishy is going on with this family, said Mike Brown of Caltech in Pasadena, US. We sure have a lot to learn about what happens to ice in the outer solar system, he added.

“I, for one, welcome our new overlords.”
hey, glad I’m not the only one.
Is that possible? TO calculate their trajectories back 1 billion years?
I will take it over our leadership we are getting soon.
at least the icy overlords can put to rest the global warming theory.

Probably not. And it’s got to be worse for these objects, because it’s largely unknown out that far, and these objects are all on inexplicable orbits.
