Question:
Stars generally move in free orbit. Since the sun is a star why doesn't it crash into planets?


Replies:
Because the planets orbit the Sun. You might as well ask why the Earth doesn't crash into the Moon.

The Moon orbits the Earth; the Earth orbits the Sun; the Sun orbits around the center of the Milky Way; and the Milky Way is moving through the universe relative to other galaxies. Stars can "crash into" each other since there are so many of them in our galaxy, and galaxies can collide, but once a planetary system has formed, it remains stable unless perturbed by another nearby passing star.
