What units of measurement do you use to measure the earth to...

Question

1. Moon
2. Galaxy
3. Sun
4. Communication satellite
5. Pluto
6. Proxima Centauri

Answer 1

Anything closer than the sun is Miles or Kilometers, the sun is 1 AU (Astronomical Unit) away, so things in the solar system can be represented in AU or miles~Km but past Mars the Miles~Km numbers get huge so AU is usually used. Outside our solar system, the AU is tiny too, and the numbers get huge, fast, so then Light Years are used.

Answer 2
