Chuhuiv Observational Station (or Chuguev Observational Station) of the Institute of Astronomy of Kharkiv National University is an astronomical observatory founded in the early 1960s near the village of Ivanovka, Chuhuiv Raion, Kharkiv Oblast, Ukraine. In 2022 the observational station was occupied and severely plundered by Russian soldiers, who during 6 months of occupation stole or damaged most of the scientific equipment [2] [3] .

The founder of the observatory was Nikolai P. Barabashov. [4] [5] The main instrument of the observatory is 70-cm reflector AZT-8. [6] The observational station hosted one of the first coherent optics processors used to reduce astronomical observations. [7] The main topics of the observations conducted on the observational station are photometric observations of asteroids and monitoring of space debris. In particular, the observations conducted here significantly contributed to the introduction of H-G1-G2 asteroid magnitude system [8] and to the discovery of the YORP effect for several asteroids [9] [10]

1620 Geographos is a highly elongated, stony asteroid, near-Earth object and potentially hazardous asteroid of the Apollo group, with a mean diameter of approximately 2.5 km (1.6 mi). It was discovered on 14 September 1951, by astronomers Albert George Wilson and Rudolph Minkowski at the Palomar Observatory in California, United States. The asteroid was named in honor of the National Geographic Society.

719 Albert, provisional designation 1911 MT, is a stony asteroid, approximately 2.5 kilometers in diameter, classified as a near-Earth object of the Amor group of asteroids. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 3 October 1911, and subsequently a lost minor planet for 89 years. The asteroid was named in memory of Albert Salomon Anselm von Rothschild, an Austrian philanthropist and banker. Albert was the second Amor asteroid discovered, the first being 433 Eros.

The Yarkovsky–O'Keefe–Radzievskii–Paddack effect, or YORP effect for short, changes the rotation state of a small astronomical body – that is, the body's spin rate and the obliquity of its pole(s) – due to the scattering of solar radiation off its surface and the emission of its own thermal radiation.

<span class="nowrap">(458271) 2010 UM<sub>26</sub></span> and <span class="nowrap">2010 RN<sub>221</sub></span> Pair of main-belt asteroids

(458271) 2010 UM26 and 2010 RN221 are a pair of sub-kilometer-sized asteroids that have extremely similar orbits in the main asteroid belt. These two asteroids are thought to have dissociated from a binary system sometime in the 2000s, which would make them one of the youngest asteroid pairs known. The largest member of this pair, (458271) 2010 UM26 (or simply 2010 UM26), is about 760 m (2,490 ft) in diameter and was discovered on 10 November 2006 by the Spacewatch survey at Kitt Peak Observatory. The smaller member, 2010 RN221, is about 350 m (1,150 ft) in diameter and was discovered on 11 September 2010 by the Mount Lemmon Survey at Mount Lemmon Observatory. It was not until February 2022 that astronomers began to recognize the similar orbits of these asteroids.
