celestial bodies which, held by its attraction, revolve
round it. The system comprises the major planets, with
their satellites; the minor planets, or asteroids, and the
comets; also, the meteorids, the matter that furnishes the
zodiacal light, and the rings of Saturn. The satellites
that revolve about the major planets are twenty-two in
number, of which the Earth has one (see Moon
two, Jupiter five, Saturn nine, Uranus four, and Neptune
one. The asteroids, between Mars and Jupiter, thus far
discovered (1900), number about five hundred, the first
four of which were found near the beginning of the
century, and are called Ceres, Pallas, Juno, and Vesta.

comets seen at more than one perihelion passage, are
