Meteor shower particles that are quickly blown away by solar radiation pressure). Recently, Peter Jenniskens has argued that most of our short-period meteor showers are not from the normal water vapor drag of active comets, but the product of infrequent disintegrations, when large chunks break off a mostly dormant comet. Examples are the Quadrantids and Geminids, which originated from a breakup of asteroid-looking objects, 2003 EH1 and 3200 Phaethon, respectively, about 500 and 1000 years ago. The fragments tend to fall apart quickly into dust, sand, and pebbles, and spread out along the orbit of the comet to form a dense meteoroid
The Dean's December The Dean's December The Dean's December is a 1982 novel by the American author Saul Bellow. The first novel Bellow published after winning the Nobel Prize in Literature in 1976, it is set in Chicago and Bucharest.
