Billy Said:

Will the planets of the Solar System decelerate when the Sun burns out?

We Answered:

Yes, ofcourse. All the planets revolves around the sun because there is a gavitrational attraction between the planet and the sun. so when the sun burns out definetly all the planets decelerate

Barbara Said:

Can a solar system have more than one sun?

We Answered:

Feeling mutual is correct, they definately do exist and to date the largest group we've found is the trinary star system... in fact, binary systems (2 "suns") are very common in the universe.

EDIT- I tend to agree with quantummc on the planets though. I would highly doubt that any planets, particular rocky earthlike planets, could form or stay together under such extreme gravitational variances. Really, I dont think that they could even form under those circumstances.. the stars would affect too much of the surrounding matter to allow for it to coallesce into planets.

Even if they did form... Rocky planets would likely be torn apart, think of our asteroid belt, while gaseous planets orbiting nearby would likely be stripped of their atmosphere by the proximity of the stars.

The only planets I would think could exist in that type of system would be ver large gas giants well outside the mutual orbit of the stars so that it was always far enough away the stars. Any internal orbit would just burn away its atmosphere and disolve the planet within a few hundred million years.... If it was even able to form in the first place.
