One round white in colour object in the sky

I saw a round shaped small moon like object in the sky. But it was much smaller than moon and much bigger to be seen as Venus. It was still day time and it was not at all dark. The object was there only like some celestial object. I took a photo too from my phone. Lot of people saw it. First many thought, that it's done weather balloon, but officials from weather department said that it was not a weather balloon. There's a report about this in the local news paper too.
