The comets are ice-rich bodies that become prominent when heat from the sun causes their trapped volatiles to sublimate. The most visible and distinctive features of comets are the coma and tail. However, most of the mass of a comet is contained within a comparatively tiny central nucleus, and it is this body that is of the highest scientific interest because of its likely identity as a planetesimal from the outer regions of the solar nebula.
