acctually,planets r part of of a star that has been datatched form the star.the earth is a part of the sun.when i first knew i couldn't believe it.its better if u read motions in 2 dimensions & laws of angular motion.then,u try 2 know about the natures of the solar system.

Planet's are not part of stars and Earth was never part of the sun.
A star system is formed from a gas cloud. When a part of the cloud becomes very dense, and collapses due to gravity and starts fusion, it becomes a star. Planets are formed from nearby (but different) regions of the cloud where the mass has collapsed, but not enough mass/density to start fusion. So, you can say that stars and planets were formed in the same way. But they formed separately and after the formation they are completely different, and neither is a part of the other.

Yes. The whole solar system is formed from a gas cloud which was the result of a supernovae i.e. when a very old star exploded. But that star is not the Sun. It was a different star at the same place, before the sun (and the rest of the solar system) was born.
