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–Ukrainian female astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj on 18 August 1972.[5]
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.[3][4]
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.[2] 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.[6]
