I saw a moving light being followed by some type of plane

I was standing outside looking at stars in parking lot and noticed that there was a small light that was traveling towards the Northeast. It was unable to see any distinct stars around the object to use as a reference and the light appeared to be lower in altitude (and therefore larger than the fixed stars). I tried to use building in close proximity to determine whether the object was in fact moving and it seemed to be traveling along that straight path for the minute or so I was able to see it. The object was slowly traveling along this (relatively) straight path until I was unable to see it due to distance & moving behind tree-line. Approximately 10-15 minutes after I had seen this object slowly moving along the Northeast, I had heard and seen a plane (not sure if military or otherwise but had lights that were different from conventional commercial aircraft) traveling extremely fast and then out of my view in the same direction as the luminous object had ! just minutes before. Then, after about 3 or so minutes the same (if not very similar) aircraft had came back at a lower altitude going in the Southwest direction and was moving very slowly.
