Two slow moving fireballs following each other parallel to the earth’s surface

Two fairly slow moving objects, one following the other in a perfectly straight line moving west to east. No sound whatsoever. Both were primarily red and white in color and looked like slow moving fireballs. Took a video on my smartphone. Zoomed in on the second object using pinch and un-pinch. Playing the video, it flashed brightly one time. Never have seen anything like it in my life. Full moon tonight over North GA. I was outside shooting street Christmas lights in our neighborhood. Looked up into the western sky as I walked home at which time I witnessed the sighting. College educated male, age 74.
