Working on a story idea that involves binary worlds. To keep the math simple I'm assuming the planets to be Earth sized, and mass, orbiting a star identical to the sun. I managed to find someone to help with the first equations and discovered that based on the time it takes them to orbit each other (48 days) they would be 702,904.853km apart, and based on their year (432 days) they are 167,323,260km or 1.1 AU from the sun. I also discovered that a full "moon" would be 8 times brighter than our moon. My question is Would 702,904.853km be far enough apart for them to rotate, or would they be tidally locked? Is it even possible for them to rotate and still be orbiting a common barycenter, and if so what would the distance be? FYI I don't need the equations( I'm 2 decades out of school) but I don't need it explained like a 5yo either. Just looking at plausibility of this.
