Comet P/2010 A2, an Activated Asteroid from the Main Asteroid Belt

Comet-like object P/2010 A2 was discovered by the LINEAR survey on January 6, 2010. Service observations carried out using ACAM on the William Herschel Telescope on January 21, 2010, show an asteroidal nucleus detached from the dust tail. Owing to its orbital parameters and its cometary appearance, the object is classified as a main-belt comet, in other words, an activated asteroid from the main asteroid belt. Comet P/2010 A2's orbit is the nearest to the Sun known so far, for this kind of object (semi-major axis of 2.29 AU). .

Spectroscopic indications of water have been repeatedly looked for from this object. As far as I have been able to ascertain, they have never been found. It is difficult to understand what could have driven 8 months of expulsive activity from p/2010a2, if not a substantial amount of water ice sublimation.

I actually do have a couple of questions for you if you usually do not mind.
Could it be only me or does it look as if like a few
of the remarks appear like they are coming from brain dead folks?
:-P And, if you are writing on other social sites, I would like
to keep up with you. Could you make a list every one of
your community pages like your Facebook page, twitter feed,
or linkedin profile?

With havin so much content do you ever run into any issues of plagorism or
copyright violation? My website has a lot of unique content I've either authored myself or outsourced but it looks like a lot of it is popping it up all over the web without my permission.

Do you know any ways to help stop content from being ripped off?
I'd certainly appreciate it.

Here is a recipe for a good face mask: 8 ounces blended pumpkins (cooked and
cooled), 12 finely chopped almonds, a quarter-full
cup of honey, and one eighth teaspoon olive oil.
This uses a wheel to force the abrasive materials against a surface.
You don't need to go to your dentist to get a quality and quick whitening treatment.
