Another, the thirteenth in a row object from the cluster of asteroids between Mars and Jupiter, the comet appeared. The discovery was presented at Tuesday, November 11, 2014, at a conference of planetary sciences department of the American Astronomical Society (American Astronomical Society's Division of Planetary Sciences).

asteroid 62412 was discovered and cataloged in September 2000 specialists Lincoln Near-Earth asteroid Research (LINEAR), located in Socorro (New Mexico). It belongs to the family of Hygeia - quite dark objects of spectral types B and C.

As the authors emphasize the discovery, it was assumed that the asteroids - relatively stable unchanging space object. However, modern technology has allowed scientists to see that the world is more diverse than it seems. Through the efforts of astronomers from the US soldier with a five-digit number asteroid turned into one of the most bizarre today solar system bodies.

"Ten years ago, everything was more obvious what the object is a comet, and what not, - said Scott Sheppard (Scott S. Sheppard) of the Carnegie Institution. - Today, things have changed, and even these have become familiar celestial bodies like comets, are much harder than we imagined before. "

Dr. Sheppard and his colleague Chadwick Trujillo (Chadwick Trujillo) of Hawaiian Gemini Observatory (Gemini Observatory) known joint opening in March 2014 of the dwarf planet in 2012 VP113, the most distant solar system. Now they are focused on the study of the origin of "comet-shifters."

Available data on the asteroid 62412 suggests that the density of the object is comparable to the density of other asteroids and comets different from density. However, the body has a high speed of rotation around its own axis, which in turn apparently causes displacement of material on its surface.



As the researchers write, perhaps this movement provokes exposure of subsurface material consisting of ice or other solid matter. Evaporating it manifests itself in the form of a cometary tail, which appeared under the influence of radiation from the Sun.

Scientists emphasize that the origin of the main-belt comets is largely a mystery, because their very existence contradicts the basic theory of the complex evolution of the solar system.

Usually comets move in highly elliptical orbits and come flying out of the depths of space, most likely from the Oort cloud surrounding our planetary system. There are also short-period comets whose path lies not nearer the orbits of the giant planets like Jupiter and Saturn.

However, recent estimates of astronomers, there is also at least a hundred yet undiscovered comets in the main belt between Mars and Jupiter.
