Hi there, welcome the KSP community. You can go to settings at the top right, then on the left there should be 'edit signature'. I am not sure how to resize images but ill take a look.
I would suggest i titan like planet (bigger then the irl thing) in the gap between dres and duna. its orbit is VERY inclined, but almost a circle. It has a think atmosphere and it has difficult visibility with some king of mountains or volcanos. It would be called trourlog.
