摘要

2016年8月至10月，来自不同经度的两名观测者合作对近地小行星(NEA) 1943 Anteros进行了CCD光度观测。分析结果表明，该小行星可能为双星，p1 = 2.86923±0.00006 h, a1 = 0.07等，p1 = 23.548±0.002 h, a2 = 0.05 ~ 0.10等，有效直径比Ds/Dp≥0.22±0.02等。

1943 ANTEROS: A POSSIBLE NEAR-EARTH BINARY ASTEROID.

A collaboration of two observers at widely-separated longitudes made CCD photometric observations of the near-Earth asteroid (NEA) 1943 Anteros from 2016 August to October. Analysis of the data led to the possibility that the asteroid is a binary with P ₁ = 2.86923 ± 0.00006 h, A ₁ = 0.07 mag and P _ORB = 23.548 ± 0.002 h, A ₂ = 0.05-0.10 mag. The estimated effective diameter ratio is Ds/Dp ≥ 0.22 ± 0.02.
