Started in mid 2003, the CFEPS project has surveyed approximately 400 square degreesof sky lying within a few degrees of the ecliptic.

This survey resulted in approximately 200 KBOs being discovered. More significantly, through the investment of hundreds of hours of follow-up resources (approximately 5-times those used in the discovery phase of the survey) resulted in the determination of high-precision orbits for approximately 80% of the KBOs in the characterized CFEPS sample. These reliable obits are essential to the scientific exploitation of the CFEPS KBO orbit sample statistics.
