3 orbs in a straight line perfectly spaced apart, all flying in unison as if it were one

Went to visit my parents in Michigan. We had a little campfire and invited some friends. We were looking for satellites and after so long we gave up and everyone was staring at the fire and chatting. Someone in our group said hey look at that so we all looked up and seen three orbs, bigger than stars, looked hazy or like some fog was over them. They had a slight greenish hue. They were in a straight line and equally spaced apart all floating in unison as if it were one. We watched it fly by at a slow to medium pace and the orb in the front as well as the orb in the back started drifting farther from the middle one, and then it was just gone. Like it just vanished. I still cannot believe we all seen that. I put it on Facebook and two family members, one from temperance Michigan and the other from Ohio said they witnessed it as well. So in total 10 of us seen this. Another thing to add is that it was very quiet and peaceful out, the craft made no noise whatsoever and there were no airplanes or helicopters in the sky at that point.
