[citation needed] Damocloids are reddish in color, but not as red as many Kuiper-belt objects or centaurs.
Retrograde objects such as Halley's Comet and damocloid 343158 Marsyas can have relative velocities to Earth of 81 km/s (290,000 km/h).
[6] Damocloids are thought to be nuclei of Halley-type comets that have lost all their volatile materials due to outgassing and become dormant.
Another strong indication of cometary origin is the fact that some damocloids have retrograde orbits, unlike any other minor planets.
[8] The list includes A/-designated objects (introduced in 2017) that were mistakenly identified as a comet, but are actually minor planets.
