Made from an MPC List of July 24, 2025

Shangri-La
On this page is my chronological version of the Minor Planet Center’s (MPC’s) Periodic Comets In Reversed Numerical Order of July 24, 2025.
Also at the MPC is Periodic Comets in Name Order.
I added a CPY—periodic Comet discoveries Per Year—number. It is on the same line as the last discovery of each year.
The default order of this list is Earliest to Latest. Hitting Toggle Earliest / Latest flips the order.
In Latest to Earliest order, the CPY number is still on the same line as the last discovery of each year, but that line will be listed before all earlier discoveries.
Half-month and discovery letter charts are in New- And Old-Style Minor Planet Designations, and in Provisional Designations at The MPC.
