Question:
How do you measure the distances between the planets up in space?


Replies:
We observe the locations of the paths of the planets in the sky. Using geometry, we can find the location. Once we know the location of each planet, it is easy to calculate the distance between them. It is like an address (coordinate) system. If you know the location of two addresses for some reference point, you can then find the distance between the addresses.
