White object in totally clear sky. Moving strangely. Not a plane. And not a loose balloon!

I have seen and documented things flying around above elk grove for 20+ years. More in the past 2 years as I have started paying attention more. Today was different, almost nightly you will see white balls moving. Some fast some slow. Not planes and not any satellite I've ever seen. I've shown them to multiple people. I am also not actively hunting or looking. I see this when I'm walking to my house after parking or out front smoking a cigarette. I have never seen in broad daylight though. Few hrs ago. Blue sky day, no clouds, I went out to have a smoke. I look up and see a plane moving east. I'm facing east. We'll off to the left of the plane I see a little white ball. First thought it was a party balloon. But then it 90 degree turned left and it startled me. Then I got out my phone. I have the galaxy 23 ultra. Best camera on a phone. My zoom takes high res moon pics ok. I zoomed in at 200x just to see what it was and it was a sphere and was moving strange hard to keep track. That's where I snapped a few pics then switched to video. You can tell how zoomed in I am due to the size of my neighbors roof shingles and it helps see its movement since I'm surrounded by 2 story homes. Object was not a party balloon. It was massive. Much higher up than I thought originally too. At least commulercial jet height. It darted off behind the roof and I lost it. Then it reappeared to the right again and went back again behind the roof and I lost it. Tried running upstairs to a window but it was gone. It had incredibly speed and was able to change direction instantly. Absolutely amazing sight to see.
