It means that the distance from the sun and the earth is 9300 miles, which means only 8 light minutes. And the distance between us and our hometown is even close.
So we are close to each other.
I sent these postcards to my friends and put their hometown in the front side and I want to know the distance between me and them, so I write the little question on the back side that '____ light minutes you think between you and me' and I got some interesting feedback from them.
The distance is both objective and subjective and we can keep the communication between each other.
