2098 Zyskin
2098 Zyskin, provisional designation 1972 QE, is a vestoid asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered by Russian–Ukranian female astronomer Lyudmila Zhuravlyova at the Crimean Astrophysical Observatory in Nauchnyj on 18 August 1972.〔
The vestoid or V-type asteroid is also a core member of the Vesta family. It orbits the Sun at a distance of 2.1–2.7 AU once every 3 years and 9 months (1,378 days). Its orbit shows an eccentricity of 0.13 and is tilted by 7 degrees to the plane of the ecliptic. Asteroids with these spectral and orbital characteristics are thought to have all originated from the ''Rheasilvia crater'', a large impact crater on the south-polar surface of 4 Vesta, which is the main-belt's second-most-massive asteroid after 1 Ceres.
''2098 Zyskin'' has a rotation period of 3.920 hours and an assumed albedo of 0.20.〔〔
The minor planet was named in honor of Lev Yur’evich Zyskin, professor at the Crimean Medical Institute, who was head of its Pulmonary Surgery Center.〔 Lyudmila Zhuravleva also discovered 1858 Lobachevsk on the same day she discovered ''2098 Zyskin''. She is a prolific astronomer with more than 200 minor planets discovered between 1972 and 1992 and (still) ranks in 61st position on the Minor Planet Center's discoverer-list as of 2015.〔
