Cardassia Prime

If you could make any planet you want, as your very own planet to live on, what would you choose, and why? (Type, location, environment, weather, atmospheric composition, continents, oceans, wildlife, geography, etc.). Also, would you share it with anyone, or keep it as a private planet for yourself?

Make one up from scratch, or if you want to, use an existing one in star trek and modify it to your liking.
