List of unnumbered minor planets: 2003 U (430–619)

This is a partial list of unnumbered minor planets for principal provisional designations assigned during 16–31 October 2003. 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 395 bodies remain unnumbered for this period.[1] Objects for this year are listed on the following pages: A–E · F–G · H–L · M–R · S_i · S_ii · S_iii · S_iv · T · U_i · U_ii · U_iii · U_iv · V · W_i · W_ii and X–Y. Also see previous and next year.
