A bright grainy ball shaped object flew upward and diagonally high into the sky closer to my building

I live on the 15th floor and went out to the terrace to look at the moon tonight. I noticed a flashing bright light in the sky. I thought it was a star at first , but noticed it was too big, it was prominent, and it was as bright as the moons light. I took 2 photos, before zooming in on it with my cell phone video, but I dud not realize that my video was not on. When I zoomed in on the image , I saw a grainy ball that got big and small. it's colors were a little scarey to me. there was a dark brown color in it . It looked creepy. The object was in my line of vision without having to look up. Then I saw in the camera it flying upwards and diagonally at a fast pace. It flew toward the direction of my building , but extremely high into the sky that it would look like a star if anyone on the ground looked at the sky. Then it flew laterally directly above my terrace but still high up in the sky . That lateral movement was much slower . It was about an hour later that it was directly above my building
I looked up from the center of my terrace. It was too close to my apartment . I got nervous and went inside my apartment.
