I know what it isn’t but don’t know what it was

The other morning I woke up early, about 4:15 and looked out my bedroom window, I saw a bright light coming towards me, the speed and height looked like a helicopter, it past by the side of the house and its side view was like its front view a bright light. I went to the front of the house and it stopped (so far I’d been viewing 15 mins or so) and for the next 20 mins it was stationery other than some horizontal and vertical movement. I went back to bed and came back after 30 mins and it had gone. When I expanded the pictures I took I could see it was globe shape. I have no idea what it was.
