2006 Polonskoya is main belt asteroid. It was discovered on 22 September 1973 by Nikolai Chernykh and named after Elene Ivanovna Kazimirchak-Polonskaya, a Russian astronomer. Polonskaya's diameter is approximately 10 kilometers.[1][2]
Satellite
In 2005, it was claimed that lightcurve observations indicate that Polonskaya has a small moon about 0.99 km in diameter.[3] However, the non-synchronously rotating binary still needs to be fully resolved in order to confirm such satellite. Alternatively, the presence of another body has also been suggested to explain the lightcurve's irregular period, which would make it a trinary asteroid.[4]
