belt-zone circulation
The atmospheric circulation typical of Jovian planets. Dark belts and bright zones encircle the planet parallel to its equator. (p. 421)
forward scattering
The optical property of finely divided particles to preferentially direct light in the original direction of the light's travel. (p. 425)
gossamer rings
Jupiter's largest and most tenuous rings of dust. (p. 428)
grooved terrain
Regions of the surface of Ganymede consisting of parallel grooves. Believed to have formed by repeated fracture of the icy crust. (p. 428)
Kuiper belt
The collection of icy planetesimals believed to orbit in a region from just beyond Neptune out to 100 AU or more. (p. 446)
liquid metallic hydrogen
A form of liquid hydrogen that is a good electrical conductor, found in the interiors of Jupiter and Saturn. (p. 422)
The volume of space around a planet within which the motion of charged particles is dominated by the planetary magnetic field rather than the solar wind. (p. 422)
The flattening of a spherical body. Usually caused by rotation. (p. 432)
The passage of a larger body in front of a smaller body. (p. 439)
The oval features found on Miranda, a satellite of Uranus. (p. 439)
One of the icy Kuiper belt objects that, like Pluto, are caught in a 3:2 orbital resonance with Neptune. (p. 447)
Roche limit
The minimum distance between a planet and a satellite that holds itself together by its own gravity. If a satellite's orbit brings it within its planet's Roche limit, tidal forces will pull the satellite apart. (p. 425)
shepherd satellite
A satellite that, by its gravitational field, confines particles to a planetary ring. (p. 435)
tidal heating
The heating of a planet or satellite because of friction caused by tides. (p. 430)
