torus

torus An object shaped like the inner tube of a car tyre or a ring doughnut: a cylinder bent into a circle and the ends joined together leaving a hole in the middle; pltori. The cross-section through the cylinder is often circular, but may take other shapes. The Van Allen Belts around the Earth are toroidal in shape. Other examples include accretion disks and the ionized material ejected from Jupiter's volcanic satellite Io, which spreads along Io's orbit to form the Io plasma torus.
