Astronomy
The wandering Stars are those
bodies within our system, which
revolve round the Sun; they
appear luminous by reflecting
the light they receive from the
Sun, and are of 3 Kinds,
namely Primary Planets,
Secondary Planets and Comets.
Primary Planets
are those bodies, which in revolving
round the sun, respect him only
as the centre of thier revolition;
thier motions are regularly
performed in tracks or paths
called Orbits, which are nearly
circular and concentric with Each
other
A Secondary Planet,
called also a Sattelite or Moon
is a body which while it is carried
around the Sun, also revolves
around a Primary Planet, which
it respects as its centre.
Comets are a
Kind of Planets which move
round the Sun in very Eccentric
orbits and in various directions,
having vast atmospheres about
them and tails of a hairy or
nebulous character, Especially
when they are near the Sun.
The Solar System
The Solar System is that in which
our Earth is placed, and in
which the Sun is supposed
to be fixed near the centre

with several bodies similar to our
Earth, revolving round him, at
differant distances. The hypothesis,
which is the only one that can
Explain all the phenomena of the
heavenly bodies, is said to have
been first taught by "Pithagoras"
after whose time it remained
many ages in obliviou, until it
was revived in the beginning of the
Sixteenth Century, by "Copernicus"
and has since been fully Established
on the basis of demonstration by
the immortal Newton.
There are
Names 11 Primary Panets in our
systems, accompanied by at least
of 16 Sattelites. The names of the
Primary Planets with their characters
