For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

| 11675 Billboyle | Discovered 1998 Feb. 15 by P. Antonini at Bedoin. |
| William Boyle (b. 1924) co-invented the CCD while at Bell Laboratories in 1969. This device has revolutionized both amateur and professional astronomy. This minor planet was automatically detected by a CCD during an amateur survey. |
