What are two units that astronomers use to measure distances in space?

Identify a situation in which each unit of measurement would be most appropriate to use.

Respuesta :

Astronomers measure things in space using light-years because there is not relative way to actually measure things in space. Which makes measuring anything in space extremely time consuming and hard work. I hope this helped. I didnt use Google and this is all from my brain. Please give me Brainliest!
