2003 UZ413 Precovery Images

2003 UZ413 Precovery Images


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:

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.
