Star lookin ufo that left smoke ring over us

So my son, mother-in-law and me are outside arguing kinda about my sons music being loud at 2:30 in morning. When my son looks up and sees what he thinks is a star but it looks fuzzy or foggy. He says why’s that star look blurry or foggy. We all 3 looked up and immediately it headed our way, freaked us OUT! So it’s about the distance of maybe a plane at this point. It then turns we see one flash of white light and then a perfect circle of smoke or fog starts to fall towards us and by this time my husband is out on porch because I started yelling for him because we 3 were already terrified at this point, and he sees this ring in sky as it’s falling and getting larger then fades away and the object (ufo) just kept moving on until out of site still with this weird haze over it. Also there were no engine noises at all! Sadly our videos couldn’t pick anything up but we got one pic of it when it was heading out of view. Barely can see it but it’s there.
