2 round light orbs flying together low in sky that separated

Stood in parking lot and watched two rounds lights coming towards us overhead.  They were very bright, mostly white with some color change to orange.  As they approached they were flying together laterally so we thought they were connected to something.  We knew it was not a plane because of how low they were in the sky and there was absolutely no sound.
The light on the left started to veer away from the other suddenly but slowly so we were very confused then realizing they were separate entities.  It veered away as the other stayed its course.  The one veering off then went behind a cloud but we could still see it and it started to make small but extremely fast zigzag patterns in the sky.  We watched it for a minute then it slowly faded away.
We turned our attention to the remaining light which continued coming overhead and then eventually also just faded away into the clouds.
