The planets in the solar system are in well-spaced out, stable, roughly circular orbits - they don't come close enough to collide with each other. Asteroids and comets, however, are on more elliptical, unstable orbits that often cross the orbits of the planets, and sometimes planets collide with asteroids and comets.
