Part I: Introduction
Welcome to the Brulian solar system. Most Coyotians are quite proud of our system. We feel that these photos, while beautiful, cannot begin to capture the majesty of our system. The Brulian system consists of a central star, five planets, two asteroid belts, and a large cloud of pre solar material. The central star, Brule, is a fairly old (6.5 billion years) low mass star with 3.5 times the mass and energy of your sun. Presently, Brule is a fairly unremarkable star, but its past history is quite interesting.
Part II: The Legend
According to Coyotian legend, long ago Brule, the sun god, and his brother Nagaicho were equal in all regards and were constantly competing for everything. The other gods decided to put an end to their petty competitions. The other gods assembled in council and planned a contest. The brother who would dance the longest and the fastest would win their favor, while the other would be relegated to lesser god status. At first the two brothers protested. They each wanted to be the sun god and felt they could share the job. Eventually the other gods convinced each of them that there could only be one sun god; so the great dance began. The dance began slowly but gathered speed, until clouds of dust, smoke, and debris obscured the event. After much time, Brule emerged much weakened, but now the only sun god. His brother Nagaicho was left nearly dead, a mere shell of himself.
Part III: Physical Structure of the Brulian System
Of course, we at the Coyotian Space Agency have a more scientific (all be it less poetic) understanding of the origins of our solar system. We know that our solar system once had two medium mass central stars. The gravity of the smaller, more dense, Brule eventually sucked the gas from Nagaicho. During this period, Nagaicho did not give up all of its mass quietly. There were a number of violent outbursts, one of which completely destroyed a small planet nearby the two stars. This destructive process formed the inner asteroid belt which we see today. In this exchange, the mass of the two stars was was reduced from 20 to 5 times the mass of your Sun. The strong solar wind generated by Brule has reduced it to its current mass over the last five billion
The inner most planet, Nagaicho, is the burned out core of a former star. It is now a very hot inhospitable boiling mass of carbonates and silicates with an atmosphere of carbon monoxide, hydrogen sulfide and sulfuric acid along with a little hydrogen and helium left over from its days as a star. It has a mass about ten times that of Jupiter in your solar system and 13.1 times the gravity of your Earth at its surface.
The next feature is an asteroid belt which was once a fairly small rocky planet. It was destroyed 5.5 billion years ago in a violent stellar outburst.
The second planet, Ia'tik, is a hot rocky place about twice the mass and 33% bigger than your Earth. It has a thick greenhouse atmosphere of carbon dioxide, water, nitric oxide, and hydrogen sulfide and sulfur monoxide. Its surface is marked with a number of large number of very active volcanoes. Unfortunately you can't see the surface through the clouds, but our space probes have mapped the surface. The planet's liquid iron core and the strong magnetic field generated by the core result in spectacular aurora displays which make the planet appear to twinkle even with the unaided eye.
Our planet, Coyote, is the third planet. It is 1.6 times the diameter of your Earth and had about five times the mass. The gravity at the surface is 1.65 times your earth. Our atmosphere is 35% nitrogen, 25% oxygen, 15% Argon, 10% Neon, 5% Helium, 5% Krypton, 3% carbon dioxide and 2% trace gasses (water and Xenon being the largest). The atmospheric pressure is about three times yours, but we need it to help keep us warm since we are almost twice as far from our sun as you are. Since our sun generates 3.5 times the energy of yours, we end up with about 1.2 watts per square meter of energy compared to your 1.4. Our days are 25 hours long and our year has 495 of your days. Our planet has a chemical composition very similar to your earth except we have a little more metal in our crust and core than you do. We have two moons. The closest moon is a very spectacular place. It is almost three times the size of your moon and is a little more than half as far away. The surface is almost completely obscured by thick clouds. It has a very dense atmosphere with 14 times the pressure of your Earth. Its atmosphere is rich many hydrocarbons and water.
Great storms driven by the 144 hour long days and cold nights on the moon cause intense lightning which can easily be seen a night from coyote. When the moon is up, it dominates the sky, providing enough light to make astronomy difficult on Coyote. The other interesting effect is every 6.1 days the magnetic fields of Coyote and its moon get together to catch the solar wind. The result is a scintillating aurora display which can even be seen during the day. The same effect can be seen on the moon three days later causing the clouds on the moon to turn all sorts of vivid colors. The second moon is about two thirds the size of yours but is ten times further away. It appears as a very bright star and is a rather uninteresting rocky place.
Uncegila and Zintkala
These outer two planets are much like Jupiter and Saturn in your solar system. The inner one is twice the size of Jupiter with five large moons and a number of smaller ones. In is a stormy dust ball. The outer most planet has vivid red, yellow and black rings. It has one Earth sized moon and a number of small moons. It is about two thirds the size of Saturn and also has very strong storms.
Past the last large planet is a dense asteroid belt that never quite collected into an other planet. Beyond that is the Ort cloud, consisting of unprocessed pre solar material. It is home to a number of large and spectacular comets.
