ASTEROID LIGHTCURVE DERIVED DATA

공공데이터포털

This is a compilation of published rotational parameters derived from lightcurve data for asteroids, based on the Warner et al. (2009) Asteroid Lightcurve Database. This is the version as of February 3, 2017. In addition to reported rotational parameters by individual papers, there is a summary file with the values adopted by Harris, Warner, and Pravec as the most likely correct values for each asteroid. The data set also contains files listing known binary asteroids, asteroid spin axes, and 'tumbling' asteroids.

EIGHT COLOR ASTEROID SURVEY

공공데이터포털

This data set contains the reflectance spectra and associated data of the Eight Color Asteroid Survey (ECAS), including results for 589 asteroids.

TNO AND CENTAUR DIAMETERS, ALBEDOS, AND DENSITIES V1.0

공공데이터포털

This data set is a compilation of published diameters, albedos, and densities for Transneptunian Objects (TNOs) and Centaurs. A total of 129 objects are listed, many with more than one entry. This version covers published values through 31 March 2013.

IRAS MINOR PLANET SURVEY ASTEROIDS V4.0

공공데이터포털

The data presented with this data set include: (a) 8210 individual sightings associated with 2004 asteroids, (b) averaged radiometric diameters and geometric albedos derived from individual observations for 1796 numbered asteroids and 88 unnumbered asteroids (as of 1983) whose orbital elements were determined using astrometry from two or more apparitions; (c) an entry for each of 120 asteroids for which there is an accepted sighting; (d) entries for each of 4677 numbered asteroids and 2632 unnumbered asteroids (as of 1985) for which associations were sought in the IRAS data; (e) A summary of the number of times each asteroid was predicted to be scanned, and possible reasons for any failure to be detected.

IMPS DIAMETERS AND ALBEDOS V1.0

공공데이터포털
