With observations at five oppositions from 2001 to 2007, the orbit of 2003 UZ413 was quite well determined. Seven images in DSS data from 1954-1996 were found close to their predicted positions.
The following astrometry was submitted to the Minor Planet Center:
K03Uf3Z 1954 07 29.32083 20 51 02.06 -16 23 38.9 261
K03Uf3Z 1954 07 29.34514 20 51 01.91 -16 23 39.4 261
K03Uf3Z 1982 09 16.59931 00 34 47.64 -06 29 28.0 260
K03Uf3Z 1982 11 14.48841 00 30 15.28 -06 55 57.0 260
K03Uf3Z 1990 08 22.45764 01 25 58.36 -02 38 03.8 261
K03Uf3Z 1991 10 01.60800 01 29 17.58 -02 34 19.2 260
K03Uf3Z 1996 10 14.62507 01 56 23.76 -00 33 27.0 260
At the end of this page are the elements and residuals before and with the new data. The new orbit is much more accurate because the object
has now been observed for 53 years instead of six years. 2003 UZ413 was numbered on 2016-02-22.
