8405 Asbolus
Orbit and classification
semi-major axis during the next 5500 years. After the encounter with Jupiter in 2700 years, the orbit becomes unpredictable.[21]
Centaurs have short
kiloannum.[22] Asbolus is currently classified as a SN centaur since Saturn is considered to control the perihelion and Neptune controls the aphelion.[22]
It currently has a
perihelion of 6.8 AU,[1] so is also influenced by Jupiter. Centaurs with a perihelion less than 6.6 AU are very strongly influenced by Jupiter and for classification purposes are considered to have a perihelion under the control of Jupiter.[22] In about ten thousand years, clones of the orbit of Asbolus suggest that its perihelion classification may come under the control of Jupiter.[23]
Predicting the overall orbit and position of Asbolus beyond a few thousand years is difficult because of errors in the known trajectory, error amplification by perturbations due to all of the gas giants, and the possibility of perturbation as a result of cometary outgassing and fragmentation. Compared to centaur 7066 Nessus, the orbit of Asbolus is currently much more chaotic.

Physical characteristics
No resolved images of it have ever been made, but in 1998
solar radiation and the solar wind
. However, fresh craters excavate more reflective ice from below the surface, and that is what Hubble has detected on Asbolus.
