SOLAR WINDS IN A VACUUM?

Solar wind IS NOT EQUAL TO wind that we have on earth. Earths wind is a moving air current. Solar wind it the energy that sun rays( also known as photons) are carrying (well at least something like this).

This video explains how gravitational tug works and shows that blowing up does not work:

EDIT:

"how does that work when there is no atmosphere to push against?" - This is where Newtons 3rd law of motion is represented at its finest. "Every action has equal and opposite reaction." ( http://en.wikipedia.org/wiki/Newton's_laws_of_moti... ). This is basic High School physics...

I was just about to ask this question myself! From what we've been taught in school, there is no wind in space, right?? So far as I know, Soral Winds only exist/are emitted my suns. So the astroid would have to be small enough to be affected by that in our solar system.

But then this brings the question, What if the astroid is traveling at an unstopable velocity?? When was the last time you saw a rock be knocked away by solar plasma? I think if we were to avert the astroid, we would need to nuke the area in front of the astroid to knock it off its path. If we get too close, the astroid could break up and cause impending doom by sending tons of smaller astroids our way.

So I'm guessing the answer to the astroid question would be that we can not destroy the astroid without destroying ourselves. But by averting its direction, we may have a chance at survival.

Hope this answered your question.

Even if solar wind (which does exist) were non-existent, there still would be RADIATION PRESSURE incident on the solar sails.

Radiation pressure occurs because light itself carries momentum. About 4.6 micropascals per square meter at Earth's orbit for complete absorption. This can amount to about 9.1 micropascals per square meter for a complete reflection.
