[November 8 AFP] the strange asteroid which seems to have two or more tails to rotate, The Hubble space telescope (Hubble Space Telescope) of the National Aeronautics and Space Administration (NASA) is used, The paper that it discovered between Mars and Jupiter was announced by the English academic journal “astrophysical journal Letters (Astrophysical Journal Letters)” on the 7th.
The ? paper says that there are six tails of the dust similar to a comet radiately extended like the spoke of a wheel in this asteroid, although most asteroids are visible only as a point of a small light.
U.S. University of California at Los Angeles which commanded ? research () [ University of California Los Angeles and ] Professor David ジェウィット (David Jewitt) of the UCLA earth space science part (Department of Earth and Space Sciences) says, “It is not believed at all that the asteroid is seen.”

Surprisingly, the structure of a tail changes dramatically in 13 days as an asteroid spouts dust.”
Astronomers think that this heavenly body named “P / 2013 P5” has blown off dust for at least five months.
? scientists say that he may be beginning to collapse since P/2013 P5 began rotation very much at high speed.
? — scientists think that the tail of these is not what has occurred by one collision.
If it is the cause, it is because dust should be spouted all at once.
After ?P/2013 P5 were discovered for the first time through the telescope in Hawaii (Hawaii), U.S., having two or more tails was discovered in the picture photoed with the Hubble space telescope of NASA on September 10, this year.
? — Professor ジェウィット says that possibly this heavenly body was made by asteroid collision about 200 million years ago.
As for the tendency for dust to blow off with sufficient vigor intermittently, this heavenly body may have seems to disappear gently.
Professor ? ジェウィット says, “In an astronomical field, if one is found, an in the future still huger number will be found.”
“it is almost certain that this is a surprising heavenly body, and it is the first one of many the things furthermore it is found someday” (c) AFP
