Hi, I help maintain the wiki page (different username than this one), and one thing to think about with regards to the "planned" number is that there's substantial numbers of satellites that are completely unknown until just before launch, either because they're a commercial customer who doesn't want to reveal business plans or whether it's a government customer wanting to launch a spy satellite with short notice given to possible other countries.
This is especially notable with SpaceX's own launches as SpaceX apparently shoves them into gaps in their schedule whenever there isn't a customer payload to launch. So suddenly long stretches of no launches can become suddenly filled with a bunch of Starlink launches.
Alternatively, many satellites are delayed (or canceled), often for multiple years, because of construction issues, regulatory issues, or funding issues (or sometimes bankruptcy). If you go back in Wikipedia history and compare what the list of launches for 2022 was at the end of 2021 versus what actually launched, there are substantial differences. See: https://en.wikipedia.org/w/index.php?title=List_of_Falcon_9_and_Falcon_Heavy_launches&oldid=1063066513 https://en.wikipedia.org/w/index.php?title=List_of_Falcon_9_... (There were 38 non-Starlink launches planned for 2022 at the beginning of 2022, and only 27 launched.)
Those tables with the "planned" column explicitly only includes launches for which there is some kind of source stating that they'll be launching on Falcon 9.
- thinkcontext 4y agoThanks that's very useful perspective. And thanks for the work keeping the wiki page up to date!

I think this was particularly exemplified by Falcon Heavy launches. I think there were supposed to be 5 in 2022. Only 1 actually made it across the line. We'll see how many happen in 2023.
