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.), Mars 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.
The principal elements of the major planets, and of the comets seen at
more than one perihelion passage, are exhibited in the following
tables: --
