Not without outside interference. A planet in orbit is effectively already "falling" ... that is, it is behaving in a manner consistent with the law of universal gravitation.
No. For one thing, stars are actually much larger than planets. Planets orbit stars such as the sun. It is possible, however, for the orbit of a planet to decay, in which case the planet will eventually fall into the star.
An eliptical orbit. In theory a planet could also have a circular orbit, but no planet that we know of has a perfectly circular orbit, although some have a nearly circular orbit.
well its because the orbit is really big and it could cover everything..
The plane with the smallest orbit is Mercury, and the planet with the largest orbit is Neptune.

No, a moon is a natuaral satellite and would always be in orbit around a planet. If it did'nt orbit the planet it would fall into the planet.

Planet Venus cannot leave its orbit by itself. A sufficiently close encounter with a object of sufficient mass will perturb its orbit. If the object is large enough and close enough, Venus (or any planet) could leave the orbit of the Sun.
Comets don't orbit a planet, they orbit the sun.

No, Venus does not orbit a planet. It orbits a star, which is our Sun. It can not orbit a planet , if it did it would be a moon

Planets orbit stars, not other planets. A planet-like object that orbits a planet is a moon.
