* The Sun is a star, and Earth orbits it. Earth is in a stable orbit around the Sun, held in place by gravity.

* The Sun is too far away. The Sun is about 93 million miles (150 million kilometers) from Earth. This distance is vast and unlikely to change significantly in the foreseeable future.

* The Sun is not moving towards Earth. The Sun is actually moving through the Milky Way galaxy, but it is not on a collision course with Earth.

However, the Sun will eventually become a red giant. In about 5 billion years, the Sun will run out of hydrogen fuel in its core and begin to expand. This expansion will eventually engulf Mercury, Venus, and likely Earth.

So, while the Sun won't physically "come to Earth," its future evolution will eventually have a significant impact on our planet.
