A spinning silverish sphere passed under my aircraft at high rate of speed, saw out window.

My flight 5/21/2021: American Airlines PHX- DCA, seat 23A (window seat left side of plane). About 20 min out from landing at DCA I saw a silverish sphere pass under our aircraft at a high rate of speed. Looked like it came at us from the opposite direction from right front of aircraft and passed under us and my wing at a diagonal. The sphere was spinning as it traveled and seemed metallic as sun glinted off it. Perhaps the size of a bowling ball (or like the Quiddich ball on Harry Potter, but not gold). I don’t know if anyone else saw, my companion was sleeping. I reported to the flight attendants when we landed a few min later. I think they pegged me as crazy. It looked a lot like the sphere in video footage released on the news today (4/21/23) over a Mid East war zone, maybe Mosul (think footage was a few years old).
