Low Amplitude Lightcurve for KM-sized Near-Earth Asteroid (285944) 2001 RZ11
Abstract
In this paper we present results of photometric observations of near-Earth asteroid (285944) 2001 RZ11. Observations were carried out at two observatories: ISON-NM (Mayhill, NM, USA) and Tien-Shan Astronomical Observatory (TShAO) (Almaty, Republic of Kazakhstan) with 0.4-meter Santel-400AN and 1- meter Zeiss-1000 telescopes, respectively. Based on the combined data set, we found a period of P = 2.2455h ± 0.0002 with a low amplitude A = 0.07 mag. Critical bulk density for this object is ñ~2.3 g/cm^3. We did not find any previously published data on the rotation period for this object.
