'Six-Tailed' Asteroid - an interesting read

Post by trynda1701 »

Found this link to a report on BBC News pages on the Stargazers Lounge forum...

http://www.bbc.co.uk/news/science-environment-24857869

...about an asteroid, Asteroid P/2013 P5, that may be in the process of breaking up!

Asteroids and comets, and dust clouds, oh my! :wink:

"Asteroid P/2013 P5"

P/2013 P5 is a designation for a comet - yet at no point is the word
'comet' used to describe this object.

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."

So, is it a comet, or asteroid?

Actually, looking into the 'Flora family of objects' on Wikipedia reminded me of this object, P/2010 A2,...

http://en.wikipedia.org/wiki/P/2010_A2

...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? :)

The BBC is frequently sloppy in its reporting of astronomical phenomena. Like the one about the "meteor" that wiped out the dinosaurs :roll: .

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.
Best wishes from Cliff
