# Why are there some NORAD catalog IDs larger than 80000 in space-track?

I was trying to find the international designator for the Starlink-2 constellation launch. Not finding anything in Celestrak I looked in Space-Track.

The following space-track.org query builder setup generated the following query.

It gives me the latest TLEs for objects with NORAD catalogue IDs above 44700, sorted by international designator. The series goes up to 44712 then jumps to 81014 and lists several thousand more designators, ending at 89496.

Many of them above 80000 have no epochs, but some have epoch years of 1983 or 1970.

Here are a few snippets of a few columns. Space-Track requires registration to access data. To register for (the free) access see this answer.
