NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)PDO binary discovery in collaboration with Petr Pravec and the Binary Asteroid Survey Group. This was the third apparition at which the asteroid was observed but only the first time that obvious evidence for a satellite was seen. The "bowing" in the orbital lightcurve is the result of the rotation of the slightly elongated satellite, which is tidally locked to the orbital period.
Estimated size ratio (satellite/primary): Ds/Dp >= 0.26. |
