Asteroid losing his material exposes more layers of its capacity.
Some rocks, for example: sulfur with friction can burn spectacular!
Our asteroid rotates and leaves tails like below film with fireworks, right?
Two main questions are: tails come from the ignition, or come from explosion? What substance is causing it??
And other questions resulting from this:
If we had a time-lapse sequence of Hubble would be clear .... can anyone have or know?
What is chemical composition of the explosive?
How explosive can be generally asteroids?
By the way, comparing the pictures you can see the difference in volume and shape of six tails (even rotation), or not?
thanks in advance for your help and explanations!
The basic composition of the fireworks is:
(...) an oxidant and combustible. Oxidizers are nitrates, chlorates, chromates and sulphates of potassium, barium, strontium, and calcium ammonium. The combustible materials are non-noble metals: magnesium, aluminum and zinc, nonmetals phosphorus, sulfur and carbon, iron sulfide, arsenic, antimony and hydrocarbons and carbohydrates. (...)
And, of course, Dyes and Binder.
Hi Seba. Nothing is burning on this asteroid because there is nothing available to serve as an oxidant. There is no atmosphere with molecular oxygen such as we have here on Earth, and no other chemical compound in the asteroid that could oxidize other stuff in the asteroid.
As I understand it, two possible explanations for this asteroid's tails are: 1) another asteroid hit it and the kinetic force knocked stuff off the surface of the asteroid; or 2) solar radiation and the solar wind of charged particles are heating the the asteroid, vaporizing stuff on the surface and possibly through cracks into the interior, and the solar wind is blowing the stuff into space.
I'm not a chemist nor a physicist, so others may be able to provide more detail and correct any errors.
May all beings be happy, peaceful, and free.
