List of unnumbered minor planets: 2004 T (100–199)

  1. Home
  2. Wiki

This is a partial list of unnumbered minor planets for principal provisional designations assigned during 1–15 October 2004. Since this period yielded a high number of provisional discoveries, it is further split into several standalone pages. As of November 2025, a total of 112 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 · Ri · Rii · Riii · S · Ti · Tii · Tiii · Tiv · U–V · W–X and Y. Also see previous and next year.
