(120132) 2003 FY128 Precovery Images

Two new images extend the arc of this well-observed TNO back to 1989.

The following astrometry was submitted to the Minor Planet Center: 

C0132          1989 12 08.51944 10 51 27.94 +07 44 13.5                      261
C0132          1996 04 10.19236 11 20 11.52 +02 12 20.4                      261
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 16 years instead of seven years (when this astrometry was submitted in 2007).
