Summary

Description
English: Size, color, and albedo comparison of the eight largest known cometary nuclei (names in white) with measured diameters, including Comet Halley for scale. Color palettes of comet nuclei are calculated from published geometric albedos and B-V and V-R color indices. The non-cometary objects Pluto, Mimas, and Phobos (names in yellow) are also included for scale. The pixel scale in the full-resolution graphic (2000x1200) is 2 km per pixel.

Elliptical objects in this graphic are shown with their a/c (long/short) axes. Hale-Bopp and 174P/Echeclus are shown in their area-equivalent elliptical dimensions, while 95P/Chiron is shown with 218 km as its longest axis (maximum diameter estimate).

  1. 95P/Chiron (218 ± 20 km – Herschel; dimensions 190 × 143 km (not used in this graphic; 218 km is used as the max semi-axis instead, with the long/short axis ratio taken from occultation constraints) ... B–V = 0.60, V–R = 0.32, p = 0.16
  2. C/2014 UN271 (Bernardinelli-Bernstein) (137 ± 17 km – ALMA) ... B–V = 0.65 (assumed), V–R = 0.46, p = 0.049
  3. C/2002 VQ94 (LINEAR) (96 ± 4 km – photometry, assumed albedo) ... B–V = 1.07, V–R = 0.54, p = 0.08
  4. Comet Hale-Bopp (74 ± 6 km – Herschel; dimensions a/b ≥ 1.72) ... B–V = 0.65 (assumed), V–R = 0.48, p = 0.081 (post-perihelion)
  5. 167P/CINEOS (66.17 ± 22.90 km – NEOWISE) ... B–V = 0.80, V–R = 0.57, p = 0.053
  6. 174P/Echeclus (64.6 ± 1.6 km – Herschel; dimensions a/b = 1.32, b/c ~ 1.1) ... B–V = 0.93, V–R = 0.48, p = 0.052
  7. 29P/Schwassmann-Wachmann (64.6 ± 6.2 km – Spitzer) ... B–V = 0.78, V–R = 0.50, p = 0.04 (assumed, colors for coma only)
  8. C/2011 KP36 (Spacewatch) (47.3 ± 17.5 km – NEOWISE + spectra) ... B–R = 1.9
