Flying objects circling

I was filming and noticed a bright object not blinking flying towards a stationary object of the same form.
The object leaves the screen a bit because I lost sight of it and comes back quickly into the video and is flying back by the object it had originally flown by. No explanation or reason and I’ve never seen anything like it before.
The second video is of the same object that night. As I was filming it around 230am as the object was stationary and if you look closely- you can see an object zoom by very quickly past the screen. Again- no explanations and when I was originally filming I didn’t even see the object pass by.
