* Sun: The Sun is the closest celestial object to Earth. It's about 93 million miles (150 million kilometers) away.

* Andromeda Galaxy: This is the closest major galaxy to our Milky Way. It's an astounding 2.5 million light-years away.

* Neptune: This is the farthest planet from the Sun in our solar system. It's about 2.8 billion miles (4.5 billion kilometers) away from Earth at its furthest point in its orbit.

Conclusion:

* Neptune is the closest to Earth compared to the Sun and Andromeda Galaxy.

Keep in mind:

* A light-year is the distance light travels in one year, which is a *vast* distance.

* While Neptune is the farthest planet in our solar system, it's still incredibly close compared to other galaxies.
