Ini kali pertama nasa jumpa asteroid yg berekor 6,astronomers nasa kata asteroid ni sedang berlegar legar di antara orbit planet mars dan jupiter,setakat ni saintis kata apa yg boleh dorang rumuskan adalah ini mungkin satu fenomena yg mereka gelar dust injection event,dianggarkan ekor itu terbentuk dari 100 hingga seribu tan debu..kajian masih diteruskan sebab kata mereka bila dah mula jumpa sesuatu yg pelik mcm ni,beberapa kepelikan lagi akan menyusul..
Nasa astronomers have announced the discovery of a “weird and freakish object” by the Hubble telescope - the first ever six-tailed asteroid, found spinning through space between the orbits of Mars and Jupiter.
Whilst comets are well-known for their tails -trails of vaporized dust and water, thrown off from the ice-coated objects as they pass through solar winds - rocky-bodied asteroids do not produce any trace and previously only been spotted as single points of light.
Approximately 100 to 1,000 tonnes of dust have been lost from the asteroid via these tails, though the main body of the object is estimated to be many thousand times more massive than this, measuring around 1,400 feet across.
"This is just an amazing object to us, and almost certainly the first of many more to come,” said Jewitt. “In astronomy, where you find one, you eventually find a whole bunch more.”
