I was laying in my hot tub with the machine off looking up and I could look up in the sky and see around sphere

I was sitting in my backyard in my hot tub with it off looking up relaxing and I look up in the sky and from as far as I could see I could see a round metallic like sphere moving across the sky right over the top of me at a high rate of speed did not make a sound there was no streaks behind it. It was quiet as a mouse flying across the sky. it was utterly amazing to see and witness. There were no lights and it was still daylight outside so I was able to see it plain as day without question.
