Yes,, that one has me a bit stumped. In the BBC report, it just says asteroid, But if you look at the link in the BBC report to the Astrophysics Journal Letters, the object is described as follows...
"Hubble Space Telescope observations of main-belt comet P/2013 P5 reveal an extraordinary system of six dust tails that distinguish this object from any other."
...and...
"As an inner-belt asteroid and probable Flora family member, the object is likely to be highly metamorphosed and unlikely to contain ice."
...have a look at the pictures at the end of the entry for what I'm talking about. Thought to have been caused by "the impact of a small meter size object on the larger asteroid in February or March 2009".
Isn't the Solar System a strange and wonderous place?
Dear Mark, Stella & Brian
All I can say is the sooner the damn thing breaks up - the better !
At least I can forget about it then.
But suppose it doesn't break up -just keeps floating around with 6 tails forever.
That might be a puzzle & a half.
Main belt comets & Oort cloud asteroids ????
Cor blimey.
