List of unnumbered minor planets: 2004 R (300–619)

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 November 2025^[update], a total of 106 bodies remain unnumbered for this period.^[1][2] 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.
