(145453) 2005 RR43 Precovery Images


Observed on four oppositions from 2001 to 2006, this TNO's orbit was quite well determined. Fortunately, potential images from the 1980s were brighter because (145453) was closer to perihelion, and the object was found on three plates in 1976, 1982, and 1983.

The following astrometry was submitted to the Minor Planet Center:

E5453          1976 11 18.44648 00 34 59.57 -27 53 53.9                      260
E5453          1982 08 20.70280 01 21 59.67 -22 17 55.8                      260
E5453          1983 10 01.61995 01 25 24.15 -21 53 22.1                      260
At the end of this page are the elements and residuals before and with the new data. The new orbit is more accurate because the object has now been observed for 30 years instead of five years.
