Abstract

We discovered 83 asteroids at the Baldone Astrophysical Observatory (MPC code 069) in 2017–2022. We studied one of the dynamically interesting Apollo (Near Earth object) observed at the Baldone Astronomical Observatory, namely 428694 Saule (2008 OS9) and the Centaur-type asteroid 330836 Orius (2009 HW77). We studied the evolution of the asteroid Saule’s rotation period, obliquity, and spin axis together with its non-gravitational parameter

2017年至2022年巴尔东天文台发现的小行星：小行星428694 Saule和330836 Orius的轨道

2017-2022年，我们在巴尔东天体物理观测台（MPC代码069）发现了83颗小行星。我们研究了巴尔多内天文台观测到的其中一颗动态有趣的阿波罗（近地天体），即 428694 Saule（2008 OS9）和半人马型小行星 330836 Orius（2009 HW77）。我们研究了小行星Saule的自转周期、斜度和自旋轴的演变，以及其与雅科夫斯基效应有关的非重力参数d a ∕ d t {\rm{d}}a/\{rm{d}}t 。此外，我们还研究了阿莫尔型小行星 2017 UW42 的轨道，它具有重要的非重力参数 A 2 A2。
