i laughed so loud the sun has gravity about 28 times stronger then earth, almost every star we see is a sun in all stages of growth and death any little sun in orbit or birth??? of our sun or anyother would be defying gravity and the laws of physics.

The planets are gradually pushed away from the sun over the span of millions and billions of years and as their orbits enlarge and the sun’s gravitational pull on them decreases they bloat up like gas giants---and then deflate and congeal as they enter the frigid zone at the periphery of the solar system.

E=MC2 As a star or sun looses or expends energy its mass decreases and therefor any planets expand their orbits, get further from the sun because of less attraction. Gradual process but nevertheless inevitable?

You would think that the blowhard sun would have expended itself long ago spewing out all that energy for billions of years. In fact, the energy increases.

Just FYI, the only reason that solar flares get shot so far out is because they don't have much mass.
To escape the sun's gravity, a planet would have to be going much faster than the escape velocity of the sun
Once it got going at that speed [escape velocity], there's nothing to actually stop it at the orbit of Mercury.
[Sleeper's quote]
All bodies of mass act like sails on ships and the sun with its solar winds push on that mass. Because of the magnetic shields around many planets the solar wind blows mostly around them, nevertheless, planets are ever so slowly nudge further away from the sun by this force---only my .02
There's not enough mass in the solar wind to nudge a planet. You don't get knocked down by the brownian motion of still air (which is about the same kind of impact on you as solar wind has on planets.)
Planets move away from their suns because of angular momentum.

Surely you are not saying that there is more going on here than E=MC2 ?
