I saw a white, spherical object moving at a steady pace while a plane was not too far behind it, going the same direction.

At 1:19pm central time I was standing outside smoking a cigarette.
I looked up past my roof, and saw a plane, leaving a long white trail of smoke.
I scanned ahead of the plane to see where it may have been going, and saw a white, spherical object moving at a consistent rate, leaving no trail, with the plane following not too far behind it.
I pulled out my phone, and began to record first the object, then I panned right to show the plane, then panned left again to show the object.
I followed the object with my camera until I lost sight of it, but could still see the plane.
It was a blue sky, with little to no clouds.
