Asteroid Families

A 3D plot of asteroid families by proper elements and colors implemented with d3.js. Shows main belt asteroids grouped naturally by their proper orbital elements semi major axis (ap), inclination (sin ip) and eccentricity (ep). The color coding is from diagnostic colors indicative of composition astar = 0.89 * (g - r) + 0.45 * (r - i) - 0.57 and i - z, calculated from SDSS filter bands u, g, r, i, z (See paper linked below for details).

Files

CSV data files

  • ast-proper.csv Comma separated list of proper elements a,e,i and colors for all asteroids from the SDSS Moving Objects Catalog that have proper elements linked from the ASTORB Database
  • ast-proper.csv Same list as above, limited to asteroids brighter than absolute magnitude H 14
  • families.csv Asteroid families with name, median proper elements and SDSS colors from Table 2 in Parker et al. The Size Distributions of Asteroid Families in the SDSS Moving Object Catalog 4 (http://arxiv.org/abs/0807.3762)
