Newbie here...

Is it at all possible that the planets circling the Sun are moving ever closer to the Sun?

If this is possible has it been researched?

If so, could it be the cause of global warming?

I have read that scientists believe that Mars at one time had an atmosphere and an ozone layer and that it was "burned off" by the Sun. (Mind you, I am over simplifying what I have read to keep this short.) So, by these beliefs the same thing could be happening to the Earth, correct?

Hi BKM-Texas,

In short, no, planets and moons move further away from the central body that they orbit as time goes by, the same way our own Moon is moving further away from the Earth.
Consider yourself lucky to be alive right now, because in the future, there will be no such thing as a total solar eclipse, as the moon will be too far way from Earth to cover the entire Sun. Total Eclipses are getting rarer as time goes on, in the past there was no such thing as an annular eclipse, but these are becoming more common and total eclipses, less common.

Vk - Thanks for that interesting info!

I do recall reading that when the two spheres first formed, the Moon was probably 10 times closer - hence appearing ten times larger in the sky and exerting an incredible tidal force so tides could be hundreds of feet high.

Which would also mean the tidal shore was even more important in terms of evolution.

It's strange to think of the moon saying this "long goodbye" to Earth. Will it go on forever? If so will the Moon eventually fall into the orbit of another planet?
