13 lights following each other in east Orlando, FL

My husband and I were sitting outside skywatching and at about 9:18pm, low in the sky, we spotted a light moving from north west to the south east.  A couple of seconds later we saw another one, on a very close path of the first one.  And a few more seconds went by and we saw another one, and another one, and another one.  In all, there were 13 of them following, not the exact path, but a similar flight path… as if they were actually following each other.  None of them blinked.  They looked a lot like white stars, but moving.
 The entire sighting lasted about a minute as we watched them go out of sight. I’ve been sky watching for years, and I’ve never seen satellites do that. I’ve seen a couple fly by, sometimes in the same direction, or in different directions at the same time, but 13 of them in a row, all heading in the same direction?  If those were satellites, I’ve never seen anything like that before.  It seemed extraordinary.
