"Juno" was discovered by Mr
Harding of Lillienthal in the
Duchy of Bremen, on the 1st September
1804. It appears like a star of the
8th Magnitude; is distant from the
Sun about 223 Millions of miles;
and performs its revolution in 4 years, 131 days.
"Piazza or Ceres"
was discovered by M. Piazza the
astronomer Royal at Palermo in
Sicily on January 1 1801. Its periodic
revolution is 4 years, 221 days, 13 hours.
its diameter, as computed by Dr.
Hershell is about 162 miles and its
distance from the sun about 263
millions of miles. Ceres appears no
larger than a star of the 8th
magnitude, and therefor cannot
be seen with the naked Eye.
"Pallas" was
discovered by Doc Olbers at Bremen
on March 26, 1802; it is distant
from the sun nearly 263 millions
of miles, and performs its revolution
round it in 4 years, 221 days, 17 hours
Pallas appears like a star of the
7th Magnitude, and its diameter
is about 110 miles.
"Venus, Juno, Ceres and Pallas"
are called Asteroids.
"Jupiter" is the
largest of all the planets and is
Easily distinguished by his peculiar
magnitude and light. His diameter
is nearly 90,000 miles; his distance
from the Sun above 485 millions
of miles; and he performs his
periodic revolution in 4332 1/2 days
or nearly 12 years. Jupiter

completes his diurnal revolution in
9 hours and 56 minutes
This planet is also
attended by 4 satellites, invisible
to the naked Eye, but through a
telescope they make a beautiful
appearance. In speaking of them
we distinguish them according to
their places, as into the first,
the second, Third and fourth. The
Eclpses of these satellites are of
considerable use in determining the
longitude of places on the Earth.
In viewing Jupiter through a
telescope, we find several streaks
or lines over his Equatorial parts,
which are called his "belts". These
are supposed to arise from the
swiftness of his diurnal motion,
which draws his clouds and vapor
into those forms.
"Saturn" was
reckoned the most remote planet
of our system, before the discovery
of the planet Hershall, now
called "Uranus". He shines but
with a pale and feeble light, his
diameter is about 76068 miles; his
distance from the sun above 890
millions of miles, and his periodic
revolution in his orbit is performed
in about 29 days [struckthrough] years, 167 days.
Saturn revolves round his axis
in 10 hours 29 minutes and
is attended by 7 Satellites.
This planet is
surrounded by a large, broad, double
and luminous Ring, at a distance
from it Equal to the breadth of the
