It Can be, the planets can come closer to the sun...
It depends on the velocity and the force of gravity the planets have
If it's faster, then the planet will go farther from the sun.
But if it goes slower, it will go closer to the sun
Like the moon..
Moon is moving away 1.5 inch/year
last 5 giga years ago, the distance between the moon and earth 17,000miles
but today it is 1/4million miles away....

According to the second law of thermodynamics, yes, the planets are getting closer to the sun as energy leaves the orbiting system. This process is so slow, however, that the sun will most likely blow up (become a red giant) before this will ever become significant.

Doubt it. Revolution occurs because the centripetal force on earth due to the sun is balanced by the centrifugal force due to earth's rotation. However, if we accept the fact that the universe is expanding, I think there is a possibility that they are actually moving away. :)
