# List of unnumbered minor planets: 2004 R (200–299)

This is a partial list of unnumbered minor planets for principal provisional designations assigned during 1–15 September 2004. Since this period yielded a high number of provisional discoveries, it is further split into several standalone pages. As of February 2022, a total of 354 bodies remain unnumbered for this period. Objects for this year are listed on the following pages: A–B · C · D–E · F · G–H · J–O · P–Q · R$_i$ · R$_{ii}$ · R$_{iii}$ · S · T$_i$ · T$_{ii}$ · T$_{iii}$ · T$_{iv}$ · U–V · W–X and Y. Also see previous and next year.
