These include (2060) Chiron (also known as comet 95P Chiron) orbiting between Saturn and Uranus; (5335) Damocles with an orbit ranging from near Mars to beyond Uranus; and (5145) Pholus, with perihelion less than Saturn's and aphelion greater than Neptune's.
In the midst of the dinner, an additional philosopher appears, a Cynic, by the name of Alcidamas, who causes a stir among the guests, then reclines with a drink, 'just as Herakles in the cave of Pholus is represented by the painters' (Symp 14).
During this labor, it was the centaur Chiron (though some versions say it was a different centaur named Pholus) who advised Hercules to drive the boar into the snow.
Examples are Chiron and Pholus. Centaurs are almost certainly scattered disk objects that Neptune tossed far enough inward that they fell under the sway of other planets.
The stories of Pholus associate him with Theseus and Hercules, and Nessus is also linked to Hercules.
Semi-hard clay and Spartina peat "reefs" These softer surfaces can support burrowing mollusks (piddocks such as Pholus sp., Cyrtopleura costata, Barnea truncata, Zirfaea crispata) and epibenthic algae (Able et al., 1988); motile organisms, such as juvenile American lobsters and American eels, also occur in this habitat and are discussed below.
Forewings of 10 species of moths occurred [greater than or equal to] five times in feeding roosts, including the greater red dart (Abagrotis alternata), the ipsilon dart (Agrotis ipsilon), the azalea sphinx (Darapsa pholus), the lettered sphinx (Deidamia inscripta), the curve-toothed geometer (Eutrapela clemataria), the white-dotted prominent (Nadata gibbosa), the gray quaker (Orthosia alurina), [TABULAR DATA FOR TABLE 1 OMITTED] [TABULAR DATA FOR TABLE 2 OMITTED] the red-lined panopoda (Panopoda rufimargo), the variegated cutworm moth (Peridroma saucia) and the armyworm moth (Pseudaletia unipuncta).
Nessus, Chiron, and Pholus, the courteous archer centaurs who guard the river of boiling blood which holds the violent against men.

Cruikshank (NASA/Ames Research Center) believes the large, distant "asteroid" 5145 Pholus fits the composition of "a giant comet nucleus that is not, and may never have been, active." In the October 1998 issue of Icarus, Cruikshank's group shows that Pholus is a close spectral match to an object covered in most places by amorphous carbon and elsewhere by a mixture of tiny silicate grains, water ice, frozen methanol (CH3OH), and complex organic matter.
