URGENT: We ran out of 5-digit catalog numbers on 2026-07-11.
The official USSF SATCAT is now at 101070.
All newly cataloged objects have 6-digit catalog numbers of 100000+ and GP data will not be available for them using the TLE format.
Please be sure to use one of CelesTrak's other formats which remove the 5-digit catalog number limitation (and finally fix the Y2K problem) and to adhere to our usage policy when retrieving any CelesTrak data.

A set of graphs and tables that show everything from the
age distribution of the latest GP data, recently decayed objects, lost
objects, restricted objects, and the mean historical age of each GP update
since 2005 Oct 21.
If you are looking for an easy way to determine which GP
groups a particular object is in, you can now search by catalog number (e.g.,
25544 for the ISS) to find all groups containing that object and see the
latest data for each group along with a table that can be used to see which
other objects are in that group.
