‘Rubber Ducky’ comet is emphasized and involves the cracking of the neck

The rubber ducky comet head has spent 4.5 billion years in trying to turn the neck. And that causes stress fractures.

Comet 67P/Churyumov-Gerasimenko, the European Space Agency investigated for two years the use of the probe Rosetta, derives its name from the dual-lobe shape that gives it a duck-like head, the neck and the body. Now, thanks to a new three-dimensional analysis of the images of the Rosetta mission, researchers believe that the comet is full of cracks, some of them piercing into her neck, as deep as 1,600 feet (500 metres).

On Earth, cracks and cracks tend to occur in the movements driven by this planet’s plate tectonics and hot, molten interior. But the Comet 67P is cold and dead inside. The gorges, the researchers said in a paper published Feb. 18 in the journal Nature Geoscience, seem to be a consequence of the two lobes, tighten and rotate against each other in different directions.

“It is as if the material in each hemisphere is the pulling and moving of each other, contorting the middle — the neck and thinner through the resulting mechanical erosion,” co-author Olivier Groussin, an astronomer at Aix-Marseille University in France, said in a statement.

At their inception, the two bodies together may be difficult and flawed. The whimsical structure with the neck-breaking of the forces in the comet’s journey through the solar system as it tumbled along for 4.5 billion years on an elliptical orbit between the Earth and Jupiter.

Interesting is that it seems like this two-lobed structure may be common in our solar system.

NASA’s New Horizons probe recently captured images of a Kuiper belt object called (486958) 2014 MU69, which is similar in many respects to Comet 67P, but it’s much further away from the sun. (The Kuiper belt is a ring shaped area in the solar system, beyond the orbit of Neptune.) That object also revealed a surprising two-lobed structure in the close-up, though the shape of the two lobes was flatter, and look more like a pancake than a rubber duck.

In contrast to 67P, although the researchers said (486958) 2014 MU69 not reveal any clear signs of stress. So, while this two-lobed structure may be common, it is not yet clear whether objects of this type always end with a neck full of stress fractures.
