In April 2005 it was renamed by its discoverer (Robert McNaught) in honour of Kridsadaporn Ritsmitchai, a then recently deceased friend and colleague at the Research School of Astronomy and Astrophysics at the Australian National University, who worked and resided at Siding Spring Observatory.

Over the past two decades, an increasing number of asteroids, based upon their orbital and physical characteristics, have been suggested as extinct or dormant comets candidates.

[4][12] The investigation of ACOs is considered important in the understanding of formation processes of cometary dust mantles and the end states of comets, so as to determine the population of Jupiter-family comets, and, to also understand the dynamical processes involved in the transport mechanism of asteroids from typical asteroidal orbits to cometary-like ones.

[4] Kridsadaporn is amongst another group of bodies [Mars-crossing (MC) and/or near-Earth object (NEO) populations] that may have originated from the main asteroid belt as fragments injected into a mean-motion resonance or secular resonance, developing increasingly higher orbital eccentricity over time resulting in the perihelion distance becoming smaller than the aphelion distances of the inner planets.

Nine (9) clones demonstrated moderate chaotic behavior jumping between the Jovian mean-motion resonances of 15:7, 9:4, and 11:5 with some orbits becoming Earth-crossers within the integration period.

The remaining six (6) clones grew in orbital eccentricity until becoming Jupiter-crossers, and then, behaving as Jupiter-family comets, they were ejected from the Solar System over periods in the order of 105 years.

[5] Earlier studies[15] suggested that comets in all stages of evolution - active; dormant; and, dead - were very dark, often reddish, objects with spectra similar to D-type, P-type and C-type asteroids of the outer Solar System with probably carbonaceous dust containing reddish organic compounds controlling their colour and albedo characteristics.

[4] Objects with a Jovian Tisserand invariant Tj ≤ 3 and taxonomic properties consistent with a low albedo, however, are not enough to imply that they are dormant or extinct comets.
