Building a Planet: Considerations for a Habitable Solar System

[dranthor]

I am building a planet that will orbit a sun and I need help My world has 11 planes/asteroids. the planet Le Bear has multiple life forms on it. It takes 378 days to rotate around the sun. My planet has a circumference of 8199.49 miles. there are 12 months of 28 days and then 1 1/2 months of festivals for the total of 378 days. Each day has 30 hours in it and each hour has 60 minutes. there are 4 moons that circle the planet Moon 1 takes 27 days to circle earth. Moon 2 takes 35 days to circle earth. Moon 3 takes 55 days to circle Earth and Moon 4 takes 77 days to circle earth. I'm figuring that the planet is similar to Earth except for the above mentioned facts. there are 9 planets not including the one I am talking about above.
So the questions I have are as follows
1. how far wold the sun be from the planet
2. What type of star would be best for the sun?
3. Assuming the planet is similar to Earth how would the moons affect tides.
4. Is it possible that another planet could also be habitable.
5. is there anything else I should be looking at? axi tilts?
thanks

Sorry I didn't see a science writing forum but if you will direct me to it I'll be glad to post this on that forum

Suggest that you look at AstroGrav because that allows you to create your solar system in simulation and answer the basics such as distance from sun, what type of star you need to support a habital zone depending on the distance, whether the moons would be in stable orbits on the parameters you note, and how far out the moons need to be for the orbital durations you mention.

I would also recommend using a gravity simulator for this. The moons you described would definitely not be stable. Moons pull on each other, so unless they're extremely tiny, they'd have to end up in some sort of stable configuration. The term you want to research is "orbital resonance."
