Minor bodies with no official numbers, updated 13-oct-26 All are assigned numbers in range 99'999'000-99'999'999. The older range 999'000 - 999'999 is no longer used, because officially numbered objects are expected to reach this range before the year 2030. All orbits were computed with JPL Horizons and then compressed into .se1 files s99999012s.se1: 99999012 2012 VP113 s99999020s.se1: 99999020 1982 YA s99999023s.se1: 99999023 1996 AS20 hs_compare -cy 20 better s99999026s.se1: 99999026 1999 XS35 s99999027s.se1: 99999027 2002 AA29 s99999030s.se1: 99999030 2013 ND15 s99999031s.se1: 99999031 2014 PP69 s99999032s.se1: 99999032 Churyumov-Ger = Comet 67P/Churyumov-Gerasimenko s99999034s.se1: 99999034 2016 HO6 , hs_compare -cy 20 better s99999036s.se1: 99999036 2014 UZ224 s99999042s.se1: 99999042 2018 VG18 s99999043s.se1: 99999043 Neowise = Comet C/2020 F3 (NEOWISE) , hs_compare -cy 20 better s99999044s.se1: 99999044 Halley = Comet 1P/Halley s99999045s.se1: 99999045 Oumuamua = 1I/'Oumuamua (A/2017 U1) s99999046s.se1: 99999046 Hale-Bopp = Comet Hale-Bopp (C/1995 O1) s99999047s.se1: 99999047 West = Comet West (C/1975 V1-A) s99999048s.se1: 99999048 2013 AZ60 s99999050s.se1: 99999050 2021 PH27 needs hs_compare.pl -n 99999050 -hel -cy 20 s99999051s.se1: 99999051 12P/Pons-Brooks = Comet 12P/Pons-Brooks s99999052s.se1: 99999052 2024 PT5 , need hs_compare.pl -n 99999052 -hel -cy 20 s99999053s.se1: 99999053 C/2024 G3-ATLAS = Comet s99999054s.se1: 99999054 Tsuchinshan/C = Comet, years 1601 - 2090, s99999055s.se1: 99999055 2017 OF201 s99999056s.se1: 99999056 29P/Schwassmann-Wachmann = Comet, years 1601 - 2090 s99999057s.se1: 99999057 3I/ATLAS = Interstellar object, years 1601 - 2090 s99999058s.se1: 99999058 2024 YR4 = near earth asteroid, range 1900 - 2049, need hs_compare -hel -yb 1900 -ye 2049 -cy 20 s99999942s.se1 99999942 Apophis (99942) only during the year 2029, to represent the close Earth encounde.
