Summary
| Description |
English: A plot of proper elements of 2,607 asteroids in the Nysa-Polana complex of asteroid families, showing eccentricity on the x-axis and inclination (in degrees) on the y-axis, highlighting the albedo of each asteroid as its color. Diameters of each circle are proportional to the diameter of the asteroid.
The Nysa-Polana complex consists of at least two subgroups of different asteroid spectral types and brightnesses. The left of the plot shows at least one family of darker B- and C-type asteroids, including 142 Polana. The right of the plot at higher eccentricity shows a family of smaller, primarily S-type asteroids in orange; this has been referred to in literature as the 135 Hertha or NysaS family. Confusingly, 44 Nysa is an E-type asteroid and does not belong to the complex or either subgroup. Proper elements and Nysa-Polana complex membership are from a dataset by Nesvorný, 2026 (https://dx.doi.org/10.3847/1538-4365/ae4bd4); diameters and albedos are provided by JPL SBDB where available (https://ssd.jpl.nasa.gov/tools/sbdb_query.html). |
