Thqnks for the interesting question. Rather than regurgitate all the
facts you are asking for, I think the best process is to send you to
NASA's excellent solar system website:
Solar System Exploration
Information on the planets can be found at:
A very nice table with much of the data you requested for each planet
can be found at:
Compare the Planets
More in-depth information on a specific planet (such as discoverer and
date, moon data, ring data, etc.) can be found by clikcing on the
planet's name in the list to the lefthand sode of the main Planet
page. For example, the page for Uranus, is at:
Uranus - Overview
Clicking the "Read More About Uranus" link at the bottom of the short
Overview page brings up even more information about interesting
Uranus - Long Overview
However, many of the "hard facts" you are looking for are best found
in the "Facts & Figures" pages (found by clicking the appropriate tab
at the top). For Uranus:
Uranus - Facts & Figures
Uranus's moons are listed at the bottom of this fact sheet. For
individual information about a moon, just click on its name in this
As for information on the "trans-plutonian belts", please click on the
"Kuiper Belt" link in the list of planets.
For information on the Sun itself, go to:
The only fact you've asked for that isn't covered yet, I beleive, is
the *age* of the planets and the sun:
FREQUENTLY ASKED QUESTIONS: Our Solar System
Quote: "The age of the planets, on the other hand, is something that
is estimated on the basis of theory. We have measured the age of rocks
from Earth, the Moon, and Mars, and the oldest rocks all show a
maximum estimated age of several billion years. Our theories lead us
to believe that all the planets formed at essentially the same time,
and that the age of the Earth and the other solar system planets is
about 4.5 to 4.6 billion years."
Age of the Sun
Quote: "03 February, 1998. Astronomers have been able to date the Sun
by applying the theory of stellar structure and evolution to data that
describe the interior of the Sun found through the study of solar
oscillations. The Sun is dated at 4.5 billion years old, satisfyingly
close to the 4.56 billion year age of the Solar System as found from
the study of meteorites."
Search Strategy (on Google):
* "solar system" facts
* age "solar system"
* "age of the planets"
* "age of the sun"
I hope this helps!

Used to the Solar System maps and graphics that I have seen since my
youth, I was not aware, until I read the chaper 2 of Bill Bryson's "A
Short History of Nearly Everything," that it is practically impossible
to render a graphic on scale of our solar system. So I decided to try
it by myself and, yes, got the big surprise that after plotting the
orbits of the 9 planets in a large cardboard, about 4.5 feet long, the
Sun had a diameter of just 0.25 mm!
In this respect found a very interesting page at:
Thank you very much for your information. It was very interesting to
see all the facts that we know about our solar system. I was also
surprised reading the facts about the structure and mechanism of our
Just one more question is remaining about the Moon and the Earth: The
size and the distance of the Moon to the Earth, and the the size and
the distance of the Earth to the Sun, and the size of the Sun, are
such that if the Sun and the Earth are looked from the Earth, both
have exactly the same apparent size (which allows the full eclipses).
Is this just a coincidence, or, as the synchronous rotation has also
