3 spheres in a row moving very fast

I was letting my 2 dogs out in our backyard (normal nightly routine) around 9:15pm. It was a clear evening. I was looking up at the sky while waiting and I
saw 3 light spheres in a row very high in the sky moving extremely fast. The size of the spheres were very similar to the stars.
Moving from the North to the South West. They stopped in the southwest direction scattered amongst each other and vanished in different directions. The timing of the sighting was around 30 seconds or so.
I am still in awe of what I witnessed. I have seen the International Space Station, satellites and space junk in the sky over the years but absolutely nothing like this ever! The speed of the light spheres was incredible. I didn't have my phone.No video or photos.
