Confirmation Images of the Near-Earth Object 2015 PK9 on 2015-08-10

The Near-Earth Object  2015 PK9 (Orbit type: Apollo ) was first observed at SONEAR Observatory, Oliveira.(MPC code Y00)  on 2015 08 10.10036. The asteroid has an approximate diameter 49 m - 110 m ( Absolute Magnitude:  H= 23.651). This  asteroid made  a close-approach  to Earth on 2015-08-07 Nominal Distance (AU) : 0.0148213183067307 (5.768 Lunar Distances). The asteroid's  Earth MOID (Minimum Orbit Intersection Distance) is  0.013686 AU (5.326 Lunar Distances). The last published Observations was made at: 2015 08 11.54955. At the time of this 122 observations have been made and the orbit has as uncertainty of  6.
