* Earth to Moon: 238,855 miles (384,400 kilometers)

* Earth to Sun: 93 million miles (150 million kilometers)

* Earth to Proxima Centauri (nearest star): 4.24 light-years (25 trillion miles or 40 trillion kilometers)

Important Notes:

* Light-years: A light-year is the distance light travels in one year. This is a vast distance, making interstellar distances difficult to comprehend in more familiar units.

* Variable Distances: The Earth's orbit around the Sun is elliptical, so the distance between them varies slightly throughout the year. Similarly, the Moon's orbit is not perfectly circular.

* Proxima Centauri: While it is the closest star to our Sun, it is part of a triple star system (Alpha Centauri A, Alpha Centauri B, and Proxima Centauri).
